Locking error when aborting with Ctrl-C

[Nicholas Allen]

Because of the memory leaks the only way to branch from subversion for a project of any reasonable size is to interrupt it with Ctrl-C and then restart. However, sometimes this causes a problem the next time it is run:

bzr branch svn://path/to/project
using experimental bzr-svn mappings; may break existing branches in the most horrible ways
bzr: ERROR: Must end write group before releasing write lock on KnitPackRepository('file:///home/nia/repo/.bzr/repository/')

Please paste the backtrace from ~/.bzr.log.

Cheers,

I've been trying to checkout a rather large svn project (30000 revs) and this bug is making it quite annoying to do so. I manage to get it for both ^C cancels and by the looks of it also general crashes due to other errors (in this case target dir already exists).
Attached is the bzr log with a successful branch, followed by the crashing one and then a branch failing due to the write lock bug.

this should be fixed in the 0.5 branch
