Description arutha 2005-12-09 12:48:29 UTC 
Version:           1.9 (using KDE 3.5.0, Gentoo)
Compiler:          gcc version 3.3.6 (Gentoo 3.3.6, ssp-3.3.6-1.0, pie-8.7.8)
OS:                Linux (i686) release 2.6.12.5

When I (un)subscribe a folder on my imap server (courier if this might be important) kmail crashes. The action is taken (on restart folder is (un)subscribed) but kmail crashes. Unfortunately I can't send a backtrace but perhaps the crash is easily found ...
Comment 1 Jos Delbar 2005-12-10 19:13:17 UTC 
Almost similar situation here, with KDE 3.5.0, gcc 3.4.4, kernel 2.6.14.

When I attempt to view the subscriptions window for my IMAP account, the windows come up for a split second and then KMail crashes.

Everything was fine in earlier versions of KMail (i.e. KDE 3.4.3 and below). Could this be due to the new namespaces implementation? When I configure my IMAP account, no personal or other namespaces are retrieved from the server.

Backtrace:

Comment 2 Carsten Burghardt 2005-12-13 17:24:30 UTC 
I either need a backtrace with debug information or a test account on a server 
that behaves like this. My test server all work fine.
Comment 3 arutha 2005-12-13 17:52:39 UTC 
Well the problem is not reproducable with a newly created test account on my own server (wanted to give you access to test). But now the strange thing: If I play with the subscriptions on the newly created account nothing happens, but if I then do anything with my own account, kmail crashes like before. This also happens if I play with the subscriptions on another server and then go back to my own server. So it seems to be a problem with my own account which I can not give you access to. I will try to recompile kmail with debugging symbols though  and try to give you a meaningful backtrace.
Comment 4 arutha 2005-12-13 19:56:35 UTC 
Ok it seems like subscription got something to do with the problem but I managed to crash my kmail by just opening my collapsed account tree. So this is what I did: Edit subscriptions and thus make kmail crash. Start KMail and open collapsed account tree -> Crash (without doing subscription related things, they only happened before the crash and on a different account). I could work around that by supplying a false password (kmail did not crash then) and exiting kmail. After restarting kmail then everything worked ok again.

Now to the original problem: If I edit the subscription on my primary account I get a crash after clicking "ok" with the following backtrace:

Is there anything else I could supply?

My back trace is not quite the same as arutha's, so we might be experiencing different problems.

In any case, here is the extra information supplied by the KMail debug build:

Created attachment 14183 [details]
output of valgrind kmail

Perhaps this output from running valgrind on kmail is of use to you. Is there
anything else I can do to help you track down this issue?
Comment 7 Carsten Burghardt 2006-01-09 13:54:18 UTC 
Any chance to test if you still get this crash with a current checkout from 3_5_BRANCH?
Comment 8 Jos Delbar 2006-01-09 18:40:59 UTC 
The latest kdepim snapshot still crashes for me. Here's a new backtrace, in case it is different:

Comment 9 Jos Delbar 2006-01-17 11:04:48 UTC 
I noticed this bug today:

Bug 107282: KMail crashes when trying to display subscription dialog for online imap account

The backtrace seems to be similar to my own. Fortunately for the reporter the problem went away, but I am still suffering from this problem..
Comment 10 Jos Delbar 2006-02-02 16:25:49 UTC 
Status update: KDE 3.5.1 still does not work for me.

When I open the configuration dialog for the IMAP connection, no namespaces are filled in. This is what the debug output says here:

kmail: getNamespaces - wait for connection
kmail: namespaces fetched
kmail: slotSaveNamespaces UGent
kmail: capabilities:(imap4,imap4rev1,starttls,namespace,idle,mailbox-referrals,scan,sort,thread=references,thread=orderedsubject,multiappend)

The IMAP server does claim to support namespaces, however.

I have another IMAP connection that returns an "<Empty>" namespace, and subscriptions work fine with this one.
Comment 11 Jos Delbar 2006-04-06 15:26:42 UTC 
Still crashes with KDE 3.5.2, compiled with gcc 4.1.0.

This seems to be the problem. Can you paste the account settings of your 
kmailrc or send it to me?
It is possible to get an ethereal log when kmail starts up and accesses the 
account (given that the connection is not encrypted and the account is 
expanded)?

According to the backtrace the subscription is not the problem but something 
with your account. Does it help to recreate the account? What is the 
backtrace of the crash you get when you expand the account?
Comment 14 arutha 2006-04-11 01:37:29 UTC 
Mh. I created a new imap account in kmail for the same real account and manipulated the subscriptions and everything is fine. I will recompile kmail with debugging later and will try to find the time to test this again as soon as possible.
Comment 15 arutha 2006-04-11 15:34:43 UTC 
Ok, here is the backtrace I got from the newest kmail version in kde 3.5.2 when manipulating the subscription on a completely different account (and server) and then opening my collapsed folder tree (for my main account). I had to enter the password and wait some time, but that could be because of the slow connection to my server at the moment.

Ok, strange things happen now :) I managed to make kmail not crash right after typing my password. Instead it now crashes when checking mail (ctrl-L). This is the backtrace. Deleting the index helps.

Comment 19 Jos Delbar 2006-05-07 23:28:40 UTC 
I can more or less access my IMAP server using the imaps KIO slave. After entering my username and password, I am presented with my home directory on the same server. There is, among other things, a 0 byte file INBOX and a folder mail. Inside the mail folder, there are 0 byte files for each of my IMAP mail subfolders. I can view these files in the embedded binary viewer and I seem to be getting a list of messages, without their contents. When I open the mail folder, I get an error message

"The server replied: SELECT failed: Can't open mail: not a selectable mailbox"

I have no idea if this is the regular behaviour for the imaps KIO slave.

In any case, I don't get any kind of crash which is more than I can currently say for KMail. :) Perhaps this can help you guys figure out where the problem is.

I get several IMAP folder subscription crashes but not perfectly reproducible. 
Running Kmail 1.9.4 on KDE 3.5.4 with SSL enabled Courier-IMAP server.

Comment 22 BJ Blanchard 2006-11-15 17:44:31 UTC 
This crash (see below) is related to IMAP subscription - and therefore am attaching it to this bug.  But I think I know how it could be avoided.

When in the IMAP subscription dialog, and the "Loading..." message is displayed, the folder list (left pane) is populated with everything unchecked - when you have hundreds of folders and it takes 30-60 seconds to load actual subscriptions.

During the "Loading.." our users proceed to select folders that they want to subscribe to (they were unsubscribed due to renaming of folder- see bug 133339), and click OK prior to the "Loading..." being completed.

Fix is simple I think - disable the OK button until the "Loading.." is complete.

BJ.

KMail 3.5.6
GCC 4.1.1
CFLAGS="-ggdb -O2 -march=nocona -msse3 -pipe -fomit-frame-pointer -fvar-tracking"

KMail crashed here too. Backtrace looks like the one from comment#15

Comment 26 Thomas McGuire 2007-04-12 00:08:29 UTC 
To comment #23: Elias, are you sure you are using the lastest KMail version (1.9.6). I am asking because all this seems to be the same as bug #133023, which seems to be fixed.

Comment 28 Alexander Haensch 2007-04-14 10:03:55 UTC 
Bug is not fixed for me. Maybe a gcc bug?
but thunderbird 1.5.10 crashes if i enable account-autocheck on my server!
Comment 29 Patrick 2007-05-05 06:46:50 UTC 
I also experience a crash every time I change something in IMAP subscriptions (KMail 1.9.6, KDE 3.5.6, Gentoo / Courier imapd 4.0.6-r2 with SSL on Gentoo). Everything is as it should be after starting KMail again after the crash.

Comment 31 BJ Blanchard 2007-10-04 20:07:40 UTC 
Same thing happens on kdepim-enterprise branch (svn from October 1st).

If the subscription dialog says "Loading...", and you try to "check" a subscription box, it crashes.

This is only happening on IMAP servers with a LARGE number of subscribable folders.  (like > 1000)

Below is a backtrace.

BJ.

Comment 32 BJ Blanchard 2007-10-04 22:16:20 UTC 
This simple patch fixes the subscription dialog to not stop after 1000 folders -  only after 10,000 now.  A little more scalable!

Its an indirect fix for those with > 1000 subscribable folders.
