Bug 293462

Application: konqueror (4.7.97 (4.8 RC2 (4.7.97))
KDE Platform Version: 4.8.00 (4.8.0
Qt Version: 4.7.4
Operating System: Linux 3.0.0-15-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
After opening a tooltip by hovering over a folder in konqueror (i use konqueror as a filemanager) and using CTRL+T to open a new tab, while the tooltip was still open, konqueror crashed. I tried this several times, always with the same outcome.

The crash can be reproduced every time.

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