Bug 310918

Application: konqueror (4.8.5 (4.8.5) "release 2")
KDE Platform Version: 4.8.5 (4.8.5) "release 2"
Qt Version: 4.8.1
Operating System: Linux 3.4.11-2.16-desktop x86_64
Distribution: "openSUSE 12.2 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

konqueror should have been idle.  There was only one open tab, and that was open to "about:blank".  The application was minimized.  I am not aware of anything else running that could have affected this.  In particular "akregator" was not running, and the computer itself was idle.

This is the second time this has happened since a recent kde4libs update.  It also crashed in similar circumstances before that update.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Konqueror (kdeinit4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
