Hmmm.  If you have no sheets, I guess there's going to be problems
with the Sheets and Objects's dialog as you've discovered.  It
wasn't a contingency that even remotely crossed my mind, given
the plethora of sheets that come with dia.

I'll have a look at what needs to be done to make it handle
this situation more gracefully.

Dia is still based in gtk+1.2, considering 2.0 was only released
a month ago.  I for one will be delighted to use non-deprecated
functions when its time to make the upgrade.

Thanks for reporting this and giving a stack trace!  Very helpful.
