This segfault occured if you dragged and dropped an icon on a toolbar then
changed the number of toolbars visible in the frame. It occurs because the
pointers in AP_FrameData to the toolbars are stale after being
rebuilt. The solution was a simple method in
ap_UnixFrame.cpp::refillToolbarsInFrameData
to set the pointers correctly. However the toolbar rebuilding code is in
XAP_UnixFrame and xap_UnixGnomeFrame which does not have direct access to
the framedata class. This means that this method must be pure virtual in
XAP_Frame.cpp.
This in turn means that I had to implement this code in all the
ap_*Frame.h headers to keep abiword compiling on all platforms. This means
some platfroms may be broken because I haven't tested them.
Sorry in advance again. We really need src/wp/ap/xp/ap_Frame.cpp.
BTW the implementation on all platforms other than unix is
refillToolbarsInFrameData(void) {UT_ASSERT(0);}
So once platform maintainers implement icon drag and dropping you'll get a
nice assert to remind you to implement this :-)
Curtesy of Hub.

Fix segfault after drag/drop toolbar icon and changing the number of
toolbars i\n the view.
