Mem leak in pixbuf engine

[Detlef Reichl <detlef reichl gmx org>]

Hi,

i think i found a pixmap leak in the pixbuf engine. The following small
program simply shows an continually updated progressbar. I also tried it
with other widgets, but it seems to be a progressbar problem.

If i watch it in xrestop with a simple color theme all seems ok, but if
i switch to a pixmap theme the number of allocated pixmaps increases
dramatically. It seems that they don't get freed.

I've tried to track it down myself, but that goes a little bit to deep
into gtk internals...

Cheers

  return TRUE;

  gtk_widget_show_all (win);

  g_timeout_add (5, (GSourceFunc) update_progressbar, prog);
