I'm seeing similar crashes when working the with the GtkBuilder files for Anjuta's Git and Subversion plugins. Everything was fine until I added a boolean property to a custom widget I use in those projects (for which there is a glade catalog in the Anjuta tree.) Ever since then, I've had this crash. I have no idea why adding one simple property to a widget catalog would cause this, but I've worked up a hack to get around it. 

It seems that for some reason, design views don't always get associated with projects properly, such that glade_design_view_get_from_project can return NULL. I assume that this should never happen, and I have no idea why it does, but checking the validity of the return of this function seems to stop these problems here, and I can load my builder files again.

Thanks, that hack is going to be the correct fix in this case.

The design view can be null when loading a project, usually
we dont expect to hit glade_widget_show() while loading a 
project, but its possible that glade_widget_show() is triggered
somehow by the backend during the load process. 

If you have git access then please commit this patch
(with a changelog entry indicating also the bug number please),
otherwise let me know I'll take care of it...

Ok, great. I've committed the patch to git.
