Description Michael Seiwert 2006-11-14 07:08:52 UTC 
Version:           1.9.5 + Features (using KDE 3.5.5, compiled sources)
Compiler:          Target: i586-suse-linux
OS:                Linux (i686) release 2.6.16.21-0.25-default

This crash in Kmail (Features Branch 1.9.5+) is not reproducible for me but it happens fairly often (> 5 times a day). It seems to happen while selecting mails, but I had also crashes while simply doing nothing. I'm using Cyrus imap server.

Comment 2 Jason 'vanRijn' Kasper 2006-11-18 15:14:25 UTC 
I just caught the same crash, I think with gdb.  This is kdepim-3.5.5+, at revision 605527.

Comment 3 Jason 'vanRijn' Kasper 2006-11-18 15:35:38 UTC 
Hm.  Okay, just caught it again.  This is, as Michael noted, just from kontact/kmail sitting doing its thing..

Comment 4 Ismail Onur Filiz 2007-02-09 23:56:50 UTC 
This is the dreaded copy_from_stream bug I unfortunately introduced with the tagging patch. I can reproduce it quite reliably. One way to reproduce if you are running a local IMAP server:
1. Select any folder other than inbox.
2. Assuming you use maildir, and users' maildirs are under $HOME/.maildir, choose any message in the inbox, e.g. $HOME/.maildir/cur/1166857707.P13573Q1.monur-tecra:2,S
3. Run perl -e '$basename="1166857707.P13573Q1"; $suffix="some-word:2,S"; for (1..50) {  system("cp","$ENV{HOME}/.maildir/cur/1166857707.P13573Q1.monur-tecra:2,S", "$ENV{HOME}/.maildir/new/${basename}$_.$suffix"); }'
4. Now in kmail, select inbox again.

This quite reliably reproduces the crash for me. It helps if new mails are filtered by some filter that takes time to do its job, e.g. a spam filter. This makes me suspect some sort of 'race condition', i.e. index file trying to be read before the updated version ( because of new mails ) is written back.

Debugging this is the first thing on my KDE to-do list, but I am short of hobby time for some time now. Hence, any help is highly appreciated.

Fixed in r633413. See also commit message to kde-pim@. The getStringPart code assumes that all of the messages *are* in the index, which isn't the case with new messages; getStringPart was accessing memory that was not mmap()ed. Added a guard for this case, but didn't cover all possible cases (no mmap available or using getLongPart).
