Comment 1 Christophe Marin 2011-04-07 14:46:26 UTC 
Is the crash reproducible ? with one mail in particular ?
Comment 2 Tobias Koenig 2011-06-04 12:21:28 UTC 
Any updates?
Comment 3 S. Burmeister 2011-06-04 12:57:24 UTC 
This happens from time to time when kmail2 is busy creating folders' indexes while one continues to other folders or starts filtering etc.
Comment 4 Christophe Marin 2011-09-24 22:46:26 UTC 
Just got this after reading a few messages then marking the folder as read. Not sure if it's related

Comment 6 Allen Winter 2011-11-29 22:47:21 UTC 
I made the following commit. Might help with this crash but I don't know.
Please test with the next release. I will backport to 4.7.4

use the safer qstricmp() or qstrnicmp() functions in place of
strcasecmp() and strncasecmp(), respectively.

Not sure if it's related to your commit but I just got this: 
kmail was trying to load a message (the 'please wait' message was displayed) and I selected a different directory

Comment 8 Allen Winter 2011-12-01 00:15:18 UTC 
I commited b2dd6557a457a26fbb071493d88133b66128ebbb to master that might help fix this.  I can't know for sure since I was unable to reproduce.
WIll also backport the fix for the 4.74. release.

so please retest in the next release and see if my commit helps at all.

Comment 10 Allen Winter 2011-12-01 17:07:21 UTC 
you found another code-path where crashes can happen.
I just made commit b2dd6557a457a26fbb071493d88133b66128ebbb in master that might help. please try again.

also backported that commit to 4.7
Comment 11 Christophe Marin 2011-12-10 00:44:02 UTC 
Short feedback: looks better now, thanks!

I didn't see any kmime related crash this week
Comment 12 Sandro Knauß 2013-10-19 21:17:16 UTC 
No news for over a year now, so I think the bug is fixed.
