Just found a new bug in Dolphin 6.1.1, if you are creating a new group and a different member tries to open ist over the link like here:

And you are using Internet Explorer, it will cause a problem and shut down the browser. That only appears with Internet Explorer (version 6 & 7) not with Firefox.
If you try to open your own Groups, it works even with IE.
Very strange bug, I tested it on different sites with different accounts, so if anyone has an idea let me know.
Best regards
