Application: dolphin (2.1)
KDE Platform Version: 4.9.4
Qt Version: 4.8.3
Operating System: Linux 3.7.0-4-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
I just wanted to tag three files (in this case a linked folder and two linked files) by marking them and selecting "add tags" in the side bar. It took about 5 min until the tag menu appeared. This is far to long. This bug may be related to the other bug I will report after: The second time it did this, dolphin crashed. I reported the the fact that it took so long as a separate bug which has the bug number: https://bugs.kde.org/show_bug.cgi?id=311201

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
