Bug 372929

Application: konqueror (4.14.8)
KDE Platform Version: 4.14.9
Qt Version: 4.8.6
Operating System: Linux 4.9.0-rc6-1.g5f5c2ad-default x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

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

Nothing special.
Only some (three tabs) websites were open.
One tab was phoronix.com.

It always crash in the same lib, like in this backtrace.

The crash can be reproduced sometimes.

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