Bug 341287

Application: konqueror (4.14.3)
KDE Platform Version: 4.14.3
Qt Version: 4.8.6
Operating System: Linux 3.17.3-200.fc20.x86_64 x86_64
Distribution: "Fedora release 20 (Heisenbug)"

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

I was trying to download tar.gz mouse pointer customization files when Konqueror crashed and I had to restart it. It crashed repeatedly for 5 - 6 times before I stopped resptoring my session and restarted it again.

The crash can be reproduced every time.

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