Do you get any error-message on your stdout (in most cases ~/.xsession-errors 
or the console)?

Shouldn't be a problem.
Do you have any problems with this server and other mail-clients? What kind of 
server is that?

Can you select other mailboxes and download the headers?

Strange backtrace, seems like kmail tries to shutdown...

Well, it seems the KDE developers are as efficient as the mail program itself!
It only took them 10 minutes to pick up my bug report :-)

I studied my ~/.xsession-errors and cut out the part that I think is relevant.
I attached it to this email.
It look likes from line 910 (IMHO!) things are going wrong.
It seems to show that problems are indeed occuring at reading of the inbox.

BTW I saved the complete ~/.xsession-errors, so if you want it I will send it
to burghardt@kde.org (about 3 MB).
I did not attacht it because of the confidential information in it (headers of 
emails etc.)

Never tried other email-clients with this server.
According to the log it seems to be a Domino IMAP4 Server Release 5.0.10.

Yes, this is not a problem. But I do not have any other mailboxes with
so many headers, the biggest one is 76 headers. Also selected a few
emails and they downloaded fine, including large attachment of  4.2MB.

extra information: I forgot to mention that I tried to shut down kmail after 
my unsucessful attempts to read my inbox. (I wanted to retry it from
a fresh start of kmail).
The little box (compressing folders) popped up in the top-left corner of the
screen, and after a while kmail crashed and the crash handler appeared.
So it is not strange that the log shows kmail trying to shut down.

Thx for your quick reply, and let me know if you need any other information.
Tomorrow at work I will clean up the inbox and see if kmail crashes.
Like this we will know if there might be a relation with number of messages.
Or shall I leave it like this to have a reproducable situation?

John

ps I hope that replying to this email updates the bug at bugs.kde.org,
     and that it handles the attachement correctly.
     Oh well, I will know soon enough... :-)

kmail_xsession_errors

I just tried kmail 1.5 with a domino 6 server and had no problems to retrieve a mailbox with 1800 mails. It doesn't matter how big the emails are because kmail only downloads the headers when you click on the folder.
I really would like to know why the connection (aka the kioslave) died but the problem is that I can't see that from the console-output. Does you system-administrator have any logs from the imap-server that shows any error? 
Does it help to clean the inbox?

Subject: Re:  kmail crashes on retrieve of IMAP mail (after process for IMAP protocol dies)

My company uses a Domino IMAP4 5.010 server (supports IMAP4rev1).
You used a version 6 server.

I experimented a bit (removing the server and adding it again to kmail, plus
reducing the number of emails in my inbox)
and now the inbox reads fine. 
However now trying to get the headers of another
mailbox causes the "process for the imap://imap.ict.nl" to crash.

Here's what I did.
AFter I add the IMAP server to kmail (after having removed it) 
and press OK in the configuration, kmail starts to retrieve the folder 
structure plus the number of emails in each folder. So far so good.

After this I select a folder, and for a particular folder the imap slave dies.
What I find so typical is that the problem always occurs in the exact same
mailfolder. Once it crashes it will keep on crashing. Almost as if there went
something wrong when the headers in the folder are read the first time from
the server and the error persists thereafter. 
BTW the number of emails in the folder at which the process for the protocol 
dies is just 10!. Therefore I do not think that the number of headers has
anything to do with it.

Tomorrow I will contact my company's system administrator and hopefully
he can shed some light on the matter by producing a log file showing a bit
more information.

BTW I really appreciate you looking into this!

*** Bug 51756 has been marked as a duplicate of this bug. ***

I have also seen this problem.  Usually I can continue working simply by retrying 
the message fetch from the IMAP server (even if I already retrieved all messages), 
but once this would not work, and then when I tried to quit KMail so that I could 
restart it (which did let me continue working, by the way), I got a crash with the 
attached backtrace (KMail_backtrace.txt with today's date on it). 
 

Created attachment 2248 [details]
Backtrace on rare KMail crash when trying to exit

Additional information:  the error "The process for the imap://MailAndNews.com 
protocol died unexpectedly." most often occurs while attempting to delete messages 
from either the "inbox" or "Deleted" folders on the IMAP server, but this is not an 
absolute requirement for this error to occur. 
 

John, Lucius, are you still seeing this with the 3.2 beta or cvs?

For my part it is not possible to verify.
I changed jobs and do not use IMAP anymore.
So you can consider it closed as far as I am concerned.

Thanks for all your trouble!

John

This crash is believed to be fixed in the current development version of kmail. Lucius, if you can still reproduce it with the 3.2 betas or cvs, please reopen this bug report.
