Bug 316231

Application: rekonq (2.2)
KDE Platform Version: 4.10.1 "release 552"
Qt Version: 4.8.4
Operating System: Linux 3.8.0-1-desktop i686
Distribution: "openSUSE 12.2 (i586)"

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

It crashed on first startup after I updated to KDE 4.10.1. I then enabled JavaScript and WebGL again as this did not solve the unstability. I could surf a little. After 3 tabs with more complex websites like Facebook it froze hard again. The duplicates presented by the crash reporter involved starting or leaving private mode browsing. I never enabled private mode. It crashed when I tried to type something into the address bar.

The crash can be reproduced sometimes.

-- Backtrace:
Application: rekonq (kdeinit4), signal: Segmentation fault
