Bug 220359

Application that crashed: dolphin
Version of the application: 1.3
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-15-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I created a resource location file (like *.url in Windows), I was adding some tags to it via the "Change Tags" link in Dolphin. I was testing different word separators for words in the tagname and Dolphin crashed when I added the tag "Angel Investor". 
I suppose it doesn't like spaces, but I didn't knew that. It would be nice if the user had some clues about what characters s/he can use in tags.

 -- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
The current source language is "auto; currently c".
