Bug 259574

I think I'm getting a better view of what's happening:

When I mark a mail as 'read', it isn't marked as read in the UI (it doesn't change color). If I let it that way, at what I guess to be the next refresh, I get a series of conflict messages.

By the way, I forgot to mention that in order to be sure it wasn't because of a bad migration from 4.5, I destroyed all the files I thought were relevant in my home directory : any *akonadi* in my home, any *kmail* in .kde4, any *mail* in .kde4 (through find path -name *akonadi* -exec rm -rf {} \;).

So this occurs with a fresh install, I guess (or I have forgotten files).

kmail 2

Same happens for me (4.6 beta2). Looks like it happens only the first time I open a folder. And all the message windows (like 30 or so) seem to be for the same mail,

Happened again. For me it looks like:

-the popup always shows the same message
-it happens on unread messages that are GPG-signed

It happens on all unread messages, as far as I'm concerned. There is no correlation with GPG-signed emails at all.

I can acknowledge this. It doesn't have to do with GPG-signed. It happens on all kind of status changes, e.g. also when you apply a filter on a message and it gets moved to a new folder due to the filter rule.

Created attachment 55192 [details]
Conflict resolution box after applying filter

The filter moves the message and marks it as read.

actually i have no idea why its shown in this situation: when i read a mail with my android, go to kmail (shown as unread), click on it -> conflict.

the question is why it just not silently syncs with the imap and knows that it was read before

Here's another situation where the conflict dialog happen a lot:

On machineA I have kmail1 configured to download messages from my POP3 account
On machineB I have kmail2 configured to leave messages from that same POP3 account on the server

Then with kmail2 I get a ton of conflicts on messages from the POP3 account.

I'm making this bug a showstopper for the kdepim4.6 release

Hi. i'm getting flooded too, using kde 4.6.4
The kmail version is 4.6.0(gentoo version) or 2.1.0(as displayed in about box).

Reading all comments, i think i should provide the following details about my configuration:
* i use imap, not disconnected
* this is the only computer connected to this imap account
* i dont use kmail-based filtering/bogofilter/whatever.
* 99% of the mails triggering the problem are not pgp signed or crypted
* i do use spamassassin on the server, so i have lines like X-Spam-Level: and such

And my problem: each time i delete a mail, i got not one, but two 'update conflict' resolution box. The first one show modification time (00:00:00 on the left), Attribute and MDNStateAttribute. The second one show lot of text that look like headers+contents from mail.

*** Bug 260800 has been marked as a duplicate of this bug. ***

For me, this happens when I use bogofilter for spam filtering.
it offers two emails. one with the x-bogosomething and one without it.

This happens a lot for me, too - much more, since I updated from VCS version to 4.6.4 - and it disturbs my workflow a lot, even while I’m in other programs.

I understand that conflicts might be hard (if not impossible) to avoid in a concurrent system, but I don’t really look at the messages myself but just click them away. So I’d need a way to say “always keep both”. 

Means: Just make sure I don’t lose data, and otherwise don’t disturb me. 

Besides: I use bogofilter, too.

Here the conflict resolution box complains a lot about 2 e-mails which only differs in the modification time.

The left e-mail has a modification time that is the same as the localtime on my system and the right e-mail has a modification time that is my localtime minus 2 hours (looks like a different timezone). Sometimes, I've seen it only once, the difference is 2 hours plus or minus 1 second (I don't remember plus or minus).

Example:
Left:  2011-06-21 01:26:17
Right: 2011-06-20 23:26:17

PS.: My timezone is UTC+2 (UTC+1+DST)
PS2.: I download my e-mails from a POP3-server
PS3.: E-mails are filtered by the filter-feature provided by kmail2

Is the time difference because of the filtering?
time 1: when email was sent.
time 2: when email was downloaded and filtered?

sorry, I mean timezone instead of time. Sender's timezone and timezone on machine where it was downloaded/filtered.

(In reply to comment #15)
> Is the time difference because of the filtering?

Maybe there is a conflict between before and after filtering, because almost all e-mails are filtered. Sometimes I add a new header and sometimes the e-mail is moved to a different folder.
time 1: is not the time when the e-mail was sent, 
        it is the time of the appearance of the conflict resolution box.
time 2: is the exact same time as time 1 (sometimes 1s later) but 2 hours earlier.

It looks like something is respecting the timezone setting of my system, at this moment UTC+2 (UTC+1+DST), and something else is using UTC.

i've fixed my own problem by changing the following setting : misc/"mark selected message as read after".
It was checked, and the delay was '5 sec'. Now, it is still checked, but with the default value of '0'.

I still have the 'conflict resolution box' from times to times, but it's really rare now. kmail is now almost usable.

Hope this helps.

My workaround is to deactivate the spam filters. After that change I didn't see the 'conflict resolution box' again.

Yes, that helped me a lot too. But now I still get conflicts in emails that reach my inbox instead of being filtered to different folders.

I moved all my mails from "Kmail folders" to "Local folders" and deleted the "kmail folders", since then the conflict dialog didn't appear again.
And I have the spamfilter enabled, bogofilter. I am not sure if this is a real fix or something else was at fault, but no more conflict dialogs for me, woohoo :)

btw I think "Kmail folders" where created by the migration from kmail1 to kmail2
btw2: be careful if you try this(moving all your mails) too, using kmail2 Version 2.1.96 and kde 4.7rc2 I had a cup of crashes and kontact sometimes eat my all my ram until it crashed

So if I understand correctly, there is more than one reason/bug which makes us see this behavior?

Any instructions from the developers for what we users can do to capture some information we can submit when bug happens (i.e. conflict window shows)?

Same here since update to 4.7.0. I can trigger it with deleting several Mails.
I even could make kontact freeze taking 100%CPU (deleting 8 Mails with pressingdel 8 times). I had to kill kontact. (I am using kmail embedded into kontact).
It is not possible to clean up these IMAP-Accounts, deleting is a great amount of work, as one either waits for each delete being finished successfully, or clicking away all thos conflict resulution boxes :/

It would be nice, if someone could tell us, how to give neccessary information to the devs. I don't know who is the bad boy here - akonadi-server? imap-resource? kmail? And how to debug this?

I also had problems with KMail from 4.7.0 but thanks to Montel Laurent for fixing many bugs (and of course other people too), 4.7.1 will work much better.

One tip: don't use mixexmaildir resource (it's slow and uses much RAM).

I still get conflics with anything that reaches inbox without getting filtered to a specific folder like Inbox/Bugs/KDE
using 4.7 branch

What is mixexmaildir?

At my case the resolution dialog even frequently hangs forcing me to terminate kmail at all. I'm not sure it is another bug or this one. Has anybody the same behavior?

For conflict resolution box (as a result of filtering) locking up the GUI, see bug 281085.

Comment #27 Yes, I see this behaviour and I'm running 4.7.0 on archlinux

@Dave Brain

I have moved to (and voted for) bug 281085 in accordance with Jonathan Marten information.

Do you mean you have not messages doubling as a result of broken filtering any more with 4.7.1? 

I still have the doubling with 4.7.1, and haven't found a workaround at my case (POP3 accounts only and predefined Local Folders). Has anybody found?

That are folders which contains mails in maildir AND mbox format.

I thought so but now I see that I only disabled the spam filters, sorry :-(

I see this all the time. This is the only client accessing my IMAP server at any given time. How can there be a conflict, and why do I care ?

Ubuntu 11.11 beta 2.

I stopped getting the conflict resolution message in kmail 4.7.2 and akonadi 1.6.2

I don't get the dialog with 4.7.2 also.. Probably because a filtering just doesn't work :-)

https://bugs.kde.org/show_bug.cgi?id=283548

I had the same impression first, it really seemed fixed. But after one of those many internet connection losses, that i get here, i got it again. It was only one box, and it came after deleting many mails. I think the connection was lost during the mail was about to get deleted.
But this seems to be the considered use case for the conflict resolution box, so all is fine. I can mark several dozens of mails, delete, and no box appearing anymore :) Or just pressing "del" as often and as fast as i want.

The only thing: Though the mail gets deleted, akonadi passes the downloaded mail to nepomuk for indexing (entirely without any use to me), which slows down things a bit and triggers CPU-load without any reason. But thats just another bug (?) :)

Happens less with the release 4.7.2 / Ubuntu 11.10 version.

getting conflicts again in kmail 4.8rc1

Same problem on Fedora 16:
$ rpm -q kdepim
kdepim-4.7.4-1.fc16.x86_64

Same here on Kubuntu Oneiric:
kmail 4:4.7.4+git111222-0ubuntu0.1

As far as I'm concerned, this should be marked critical; "cannot use spam filtering" is almost exactly equal to "cannot use kmail".

Also, looking at Comment #9 - not being able to leave on server is a showstopper.

Also, looking at Comment #9 - bug was not a showstopeer for 4.6 or 4.7 -- maybe finally make it one for 4.8?

Also, I may be able to help; any pointers?

Thanks,
Shai.

Is anything happening with this bug? There has been no feedback from the developers giving the impression that this is being ignored.

In my case, I get the dialog box on just about every message I open. And if that message has lengthy attachments, the whole KMail system stalls until the dialog box appears - this can be for up to a minute.

For me, this should be top of the Most Hated Bugs list as it makes KMail close to unusable.

For me with 4.8 the dialog has appeared few times only (3-4 times). I use Arch Linux which follows closely to upstream releases. Just yesterday have upgraded to 4.8.1 and have not any statistics for this version yet.

FYI: Running fully up-to-date Fedora 16 w/ KMail 4.7.4

I am getting this with:
Xubuntu 11.10
KMail which reports itself as "Version 4.7.3 Using KDE Development Platform 4.7.4 (4.7.4)"
Package: kmail 4:4.7.4+git111222-0ubuntu0.1

An email downloaded using POP3 caused the "Conflict Resolution" pop-up.
I have no specific filters to handle this email, although I do have bogofilter installed.
The only difference between the two identical emails is:

---------------------------------

I'm seeing this a few times a week on a busy POP3 account using 4.8.2 with Kubuntu 12.04.

The emails are not the same, and I don't know why I'm even being given the choice -- I always click "Keep both".

it's happening a lot again in kde 4.8.4 when an email is passed through spam filter but not filtered to go to a specific folder (other than the Inbox folder).

I see it happen often when receiving mail in threads I've marked as Ignore and when doing Bogomail filtering.

Ironically, I don't even want to do Bogomail filtering on the busy account (with the ignored threads), but due to bug 285802 I have to have filtering on all accounts or none (see my comment 6 there).

KDE 4.9.0
Gentoo

Using Spamassassin (spamd) I get this 65% of the time, left one is usually after spamd touched it and the right one is before spamd touched it as evidenced by the changes in the headers and sometimes subject line.

It would be nice to never see that again, but really anoying is it hiding behind other windows and not getting noticed until after I've already futzed with kmail wondering what is up now...

Thanks in advance.

KDE 4.9.1
Gentoo

The conflict resolution box still appears a lot in 4.9.1...

Thanks in advance.

I'm seeing a trend.

I use spamassassin (spamd) and the conflict resolution box appears on messages that a subsequent filter moves the message into a different folder.

The one on the left is after spamassassin has modified it, when I click accept trhe left one, then the message(s) are moved in the destination folder for messages.

Don't know if that helps any.

Thanks in advance.

In addition to what I mentioned in comments 49,50 and 51.

Seems to also be limited to messages that are to be moved into a Folder (mailing list) that contain a lot of messages.

I have one folder that contains 12700+ and another with 6700+ messages and it seems to be limited to those particular messages.

Thanks in advance.

I can confirm this problem on ArchLinux, using KMail/Kontact that comes along KDE 4.9.1 (most recent stable as of writing). The ArchLinux installation is brand new (inside a virtual machine) and has therefore no legacy configuration files. No fancy mail setup (e.g. using SpamAssassin) has been set up. The IMAP server is UW-IMAP 2007b~dfsg-4+lenny3, the mailbox contains just about 10 mails.
The conflict resolution box appears when marking several mails as read (KMail is configured to *not* mark mails as read automatically when clicking on them in the list, but only when the user performs the "Mark mail as read" action) and immediately thereafter selecting/clicking on one of those mails in the list.
My guess is that the status change from Unread to Read is not yet transferred to the mail server, but the clicking on the mail triggers fetching the mail from the server. Thus, both versions differ when one is read (the local one) and the other is unread (the newly fetched one).

As a step towards fixing this bug, I would like to see the difference between both mails visualized better. A previous comment remarked the different widths of both emails in the conflict box, which makes it hard to spot the actual difference. Is using the widget from Kompare or KDiff3 an option? For developers (and for bug reports), the difference should be provided in a "diff"-like format.

In other words, one is locally filtered and one isn't

I found another way to reproduce this.
Start a new 'check mail' while the old one hasn't finished yet.

The generic conflict issue that appears when flags get conflicted is fixed. The second when local spam filter duplicates the message and creates weird stuff is fixed in 4.10 and will be backported to 4.9.3 soon.

This still happens to me in latest build from KDE/4.9 branch.
It also happens if kmail checks for new emails when previous operation is still in progress.

Hav you updated all kde pim modules (kdepimlibs, kdepim-runtime, kdepim) and restarted akonadi? Can you post a screenshot of the dialog coming up?

Yes. I will post a screenshot if it happens again.
There is also a chance I am running to https://bugs.kde.org/show_bug.cgi?id=305073 as well as a conflict.
I will see if it happens again after a new build. thank you.

Actually we should always disable the conflict dialog when a filter modifies a mail.
Mail (bodies) cannot be modified from anywhere else and flag changes do not
worth the conflict dialog.

I am having trouble with this with Kmail 4.14.1 and KDE 4.14.2.  The conflict resolution dialog pops up behind the Kontact Kmail window and waits for a response to be made, making Kmail cease to be usble until I minimize everything and find the popup dialog.  I would like to be able to set the default to keep both if I want so I don't have to find this dialog, or have the dialog box come up on top so I don't have wonder why Kmail is not responding and go hunt for the dialog box.  I am not sure yet while this is happening.  This long old bug report may help me figure it out after I read it all.
