--- Comment #10 from Merlijn van Deen valhallasw@arctus.nl --- OK, that's strange. I would expect it to be related to this commit:
https://github.com/wikimedia/pywikibot-core/commit/aea29ea9ecf83d509698b2a78...
but that's from October (I'm not sure which svn version that is -- sorry).
I *think* something got out of sync between your filesystem and svn, but I'm not sure why or how. Maybe github's svn bridge is not as stable as we would hope...
