Crash during rescanning shares

[helge.preuss@…]

I have a large share directory, on an external USB disk. Some time during the rescan nicotine+ crashes reproducibly. I cannot say whether it crashes always at the same point, though. The backtrace suggests that the problem has to do with the vorbis module:

Uninstall the pyvorbis package. It's the cause of that crash.

[quinox]

Try emerging pyvorbis again, most likely the module has become incompatible with your python
