crash while searching

[ebfuwx202@…]

I'm using nicotine from the Debian archives with the python optimizer installed.

I search for the word 'Voodoo' and I get a crash. Here is the backtrace:

The crash was repeatable, that is how I got the trace, but it might be dependend on a file someone is sharing.

Obviously this could also be a Python, Pygtk or cairo bug.

I get a crash also. I don't have a backtrace but it seems to be a problem with Pango and fonts. I do have what is output in the terminal:
