-- Information about the crash:
- What I was doing when the application crashed:
filling in tags for a bookmark. I had just open bookmarks with the ctrl+B and had filled in the tags in the comment section, hit enter and bam Konqureror was gone!

The crash can be reproduced every time.

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