Application: konqueror (4.8.4 (4.8.4))
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-26-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I clicked with right mouse button over top toolbar inside konqueror, while viewing some text file.
I clicked exactly over "overwrite???(do not know this name in english) button (this one do not have icon). Received "Segmentation fault (11)"
If need, I can send a video about, just guide myself.

The crash can be reproduced every time.

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