«Unknown exception encountered»

While doing "hg in" for my clone of the Vim repository, I got the 
exception below. Repeating the operation worked normally (also shown). 
I'm not sure if it's a Mercurial bug, a Python bug, a bug somewhere 
else, or even if I should leave it at that. Please don't tell me to 
upgrade Mercurial: I know it isn't the latest and greatest, but it's the 
Mercurial version that comes with my Linux distro (openSUSE 12.1).
