The bug is this line (wikipedia.py):
elif self.site().has_api() and self.namespace() in [2,3] and ( '.css'
in self.title() or '.js' in self.title()):
The bot username must be excluded in those title checks.

Hi;
My bot crashes while trying edit its own .css user subpages. An error
requesting sysopnames['wikipedia']['es'] in user-config.py appears.
Regards!
