Description Oliver Putz 2008-01-24 03:58:50 UTC 
Version:           1.9.50 (using 4.00.80 (KDE 4.0.80 >= 20080104), Gentoo)
Compiler:          i686-pc-linux-gnu-gcc
OS:                Linux (i686) release 2.6.23-gentoo-r3

Whenever I try to apply all filters (CTRL+J) on a folder within my IMAP account, KMail crashes. This bug seems to be related to the bugs bug #156319 (almost same backtrace) and bug #156291 (same backtrace, but bug #156291 already was fixed long ago...). Note that 

- KMail does *not* crash if I apply filters on a local Mailbox (even if the filter moves the mail to an IMAP account)
- Kmail does *not* crash if I apply only a single filter on an IMAP Mailbox.

The backtrace and valgrind output during the crash are:

Backtrace:
Application: Kontact (kontact), signal SIGSEGV
