Thanks for the information Herbert. We continued looking at this today, but we
still have not determined the reason it is crashing. The application crashes at
SidebarController::notifyContextChangeEvent in SidebarController.cxx at
maRequestedContext =Context {...}. Our debugger says that eEvent is of the
value <ERROR>.

I haven't fully caught up with everything, but if I had to debug this I'd watch
out for exceptions thrown in step 5 and later. In gdb I'd use the command
catch throw
to find the throwing code. Is there a similar facility in Solaris Studio?
