Comment 5 for bug 522637

Just a note that I'm recently getting this problem from lp:exaile. I ran the upgrade locally (bzr upgrade lp:exaile) because I didn't notice the "upgrade branch" link, using bzr 2.1.1. My local branch was on a shared repository, if that's relevant. The remote branch was migrated from svn a long time ago, but I don't know using which tool.

I've thoughtlessly deleted my old repository and can't restore it from a backup, but I've pointed users here if they are experiencing the problem and can help with testing stuff.
