Bug 322536

Application: konqueror (4.10.5)
KDE Platform Version: 4.10.5
Qt Version: 4.8.4
Operating System: Linux 3.9.9-302.fc19.i686 i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed: I was logged into KDE as root using Konqueror to log into Facebook. Konqueror crashes after entering the second digit of login name everytime. It doesn't matter what name I used, on the second digit it crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: Konqueror (konqueror), signal: Illegal instruction
Using host libthread_db library "/lib/libthread_db.so.1".
