glade-gtk2 crashed with SIGSEGV in g_type_check_instance()

[Chris]

In Ubuntu 12.04 Glade freezes about once every 5 to 10 minutes while in use.

I've not noticed any pattern to what causes it to freeze (not very helpful for a bug report), except it only seems to freeze while in use (as opposed to freezing while in the background).

When it freezes, it becomes unresponsive and doesn't redraw itself if the window is resized.

This is the file I was editing when glade crashed most recently. https://github.com/ccouzens/Totem-Music-Library/blob/fa29467c347a56c36eb3109bd3cb3837b715e469/musiclibrary.ui
