With trunk my application now gives lots of tracebacks when using the 
main menu, which has some images set, though not using an imagelist:

ERROR in LCL: TGtk2WidgetSet.CreateBitmapFromRawImage Incompatible 
BitsPerPixel

This is using GTK2. Has the implementation of the main menu changed 
significantly? Unfortunately this is slightly tricky to debug, as the 
entire desktop freezes.
