I have a git-svn repository which I initially cloned via a different client (not sure whether it was TortoiseGit or Msysgit). I then opened this repo in Sourcetree (0.9.2.1) and it does show the Subversion & git-svn remote in the left panel, but if I do Pull/Pull from remote: Subversion then it doesn't show the subversion URL (nor does it let me edit the field) so it won't proceed with the pull. The Mac version (1.5.8) shows the URL correctly and lets me pull. I have similar problems with dcommit/push.
Are there any other extra steps I need to do to inform Sourcetree of the git-svn metadata?
