Description Adrian von Bidder 2009-02-04 20:27:07 UTC 
Version:            (using KDE 4.2.0)
OS:                Linux
Installed from:    Debian testing/unstable Packages

Debian's KDE 4:4.2.0-1 packages from experimental.

kmail crashes sometimes (haven't yet figured out how to reproduce - sometimes it crashes, sometimes it doesn't) when I enter a folder by clicking on the folder list.

I'll attach the crashdump.

cheers

crash dump of one instance of the bug.

Oh yes: this is dimap over SSL against dovecot (Debian package 1:1.0.15-2.3) with mbox storage.  Although judging from the crash it seems to be a qt problem, not a backend problem.

Comment 3 Dario Andres 2009-02-04 21:13:00 UTC 
What is your version of the Qt package ?
Look at bug 182857 comment 1
Comment 4 Jaime Torres 2009-02-04 21:14:52 UTC 
Does the distributions know about qt-copy and the patches kde developers do?

Please take a look at bug 174065

If debian unestable does not have patch 
0256-fix-recursive-backingstore-sync-crash.diff 
please fill a bug report in debian for them to include it.
Comment 5 Adrian von Bidder 2009-02-04 21:23:00 UTC 
Yodel!

Just saw it myself: it is indeed #174065 and is fixed in Debian's qt 4.4.3-2 (I still had 4.4.3-1 on my system, I only checked that all KDE packages were current but forgot Qt.)

thanks & sorry about the noise.
