I'm not sure if the usual protocol is to provide notice about submitted patches here or not but I recently submitted a patch (http://developer.berlios.de/patch/?func=detailpatch&patch_id=2166&group_id=5358) to fix a non-critical but real bug (http://developer.berlios.de/bugs/?func=detailbug&bug_id=11934&group_id=5358) in some of the handling of ArtProvider stuff for Toolbars. This patch "seemed to work fine for metm".
Thanks for the patch. I haven't had much time to investigate it before but from what I've seen your solution (maybe not only inside wxToolbar but in wxBitmapIconProperty) is correct.

Ok, I've fixed that (little bit different from your). It worked for me but since I don't have debug wxWidges library I can't be sure. Could you test if the fix works ?
BYO
Thank you byo, that seems to have solved the core issue with the wxArtProvider stuff.
One side issue, though, is that the #include for <wx/artprov.h> isn't being generated in the resulting cpp code.
