Bug 254057

Application: konqueror (4.5.2 (KDE 4.5.2))
KDE Platform Version: 4.5.2 (KDE 4.5.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Cancelling several 'Open with/Save...' dialogues that had popped when I was downloading a document.

- Unusual behavior I noticed:
I opened the link only once, but several 'Open with/Save...' dialogues appeared in rapid succession.

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