This crash can reproduce.
step 1: Create a wxWidgets project with frame based, and using wxSmith.
step 2: Resources > wxFrame > Style, hit the "+" icon, and choice any option, like "wxCAPTION", e.g.
step 3: Close project
step 4: CB crash!
I'm testing CB 10.05 and not have this issue.
And testing wxSmith r6700, or wxPropGrid r6345, both have this issue.
If disable CC plugin, the crash still existed.
I can't find the reason, and can't to fixed.
It's seems happen when move wxPropGrid into SDK?? I am not sure... :?
