Re: SegFault in CVS-snapshot

["Torben H. Nielsen" <torben nielsen rocketmail com>]

Hi!

I've just tried stepping through the 
on_sheets_dialog_object_button_toggled() until i got the SegFault in
case
anybody can use the information for anything.

Btw. I don't think I've mentioned that I'm using Mandrake 8.2 if it
matters.
