Detlef, looks like you are correct here. It seem that I know the reason
of that. There is bug in setting GDK_GC_TILE field in GdkGC. When this
field is set, reference count of pixmap that passed as tile value is
incremented but it's not decremented in finalize of GdkGC. The
corresponding code is located in gdk/GdkGC.c

If you can suggest a patch or even file a bug to bugzilla about that, it
would be just nice.
