Application: juk (3.7.1)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-27-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

Open juk with:
1: juk /path/to/folder/with/lots/of/albums/from/different/artists
2: Click the column headers to show the Filename full apth column. 
3: Sort by full path
4: Select all the files of a particular artist
5: Right in the Artist field on one of the files in this set, click Edit Artist
6: Type in something, Enter
7: Confirm that you are editing multiple files, if asked. Click Do not show again.

8: Now, while it is still writing the ID3 tags of the selected set of files, select a new set of files. Right click Album (or something else) and edit it.

9: Repeat until Juk crashes.

Almost always it crashes on two threads, but sometimes it takes more than two threads.

The crash can be reproduced every time.
