Unidentified image error

There was a problem with the command, a python error, here is the log

I understand if you don't want to take time to fix this, but if you want to fix it you have the log now.
It doesn't seem easily reproductible, and happened with the xkcd --random command

Do you know which xkcd was used?

No sorry, it's from a long time ago too
