[Bug 79201] Konqueror crashes randomly

[Martin Böhm]

Public bug reported:

Binary package hint: kdebase

Konqueror on my Kubuntu Feisty system crashes relatively randomly, I
cannot find a pattern in the crashes. I run a standard Kubuntu system,
only my widget style is different (Polyster - I can't tell from the
backtrace if that may be a problem).

The backtrace:

Using host libthread_db library "/lib/tls/i686/cmov/libthread_db.so.1".
[Thread debugging using libthread_db enabled]
