Subversion mirror fails on .run/stash.config

[Bartosz Bielecki]

When trying to migrate I got a lovely:

Command Failed : Host Software / trunk
/opt/atlassian/bitbucket/home/shared/data/repositories/1/subgit/.run/stash.config

Log show:

Any reason why? Apart from the fact that there is no stash file present?
