Comment 3 for bug 958551

After I issued the 'bzr commit' command, it showed the output I posted.
After the ' modified swat/lang/tr/help/welcome.html' line:
 - it took some time.
 - It briefly showed '| Saving data locally - Stage 2/5 ' (and it wnet away again).
 - Soon after that the crash output was shown.

I did not had the change to enter a commit message yet. You question gave me the idea to trying to directly enter a commit message in the command:

$ bzr commit -m "test"

which works (no crash).
Please let me know if you require more tests/information.
