 Hi,
 I wrote a plugin that implements a new sort method in pidgin. However I
 would like to reset the original sort method when the plugin gets unloaded
 using purple_prefs_set_string. That causes the buddy list to be redrawed
 which crashes pidgin for one of my friends. This occurs on Windows and
 Linux.
 I don't really know how to reproduce the crash but using her .purple
 directory does it.

 I wrote a minimalistic plugin which just tries to set the preference and
 crashes Pidgin this way.
