licq crashes after file transfer

[human]

today licq just crashed after clicking Ok in the file transfer dialog

[erijo]

The file licq.debug_rw_mutex is from some older crash (doesn't include a time stamp as the other files do). And licq.backtrace.gdb is empty.

While trying to reproduce this I manage to get this when pressing the ok button (on the sender side)
