Repeatedly right clicking on multiple selected tracks causes segfault

[Dustin Spicuzza]

This is pretty neat. Just select a few tracks in the playlist, and right click a bunch of times. The menu will double in size a few times, and at some point on my machine it segfaults with

(exaile.py:5986): GLib-GObject-CRITICAL **: g_type_instance_get_private: assertion `instance != NULL && instance->g_class != NULL' failed

Anyways, pretty neat bug. Probably a threading issue of some kind?

I was able to reproduce this issue.
