Re: Segmentation fault in code - possible bug?

[Joseph Turner <joeman leederville net>]

Sorry,
Got some help - it isn't a bug. 

Needed to use a different signal function, one that disconnects
after the widget specified is destroyed.

i.e. g_signal_connect_object

Thanks to the guys on #gtk+

All makes perfect sense now.

Joe


P.S. Learnt lots because of it!
