X 8bpp displays: assertion `style->ref_count > 0' failed

[Ullrich Hafner <hafner informatik uni-wuerzburg de>]

Hi,

I have problems with an application that uses a private color map on
an 8bpp display. After installing the private color map with 

      gtk_widget_push_visual (gdk_rgb_get_visual ());
      gtk_widget_push_colormap (gdk_rgb_get_cmap ());

I get a lot of messages of the form (only if X is set to 8bpp):

Gtk-CRITICAL **: file gtkstyle.c: line 575 (gtk_style_unref): assertion `style->ref_count > 0' failed.

This error messages are not shown if I start X with 16bpp or if both
code lines are removed. Since this error also appears in the testgtk
application (start testgtk, push color-selection, push cancel) I
believe that this behavior is a GTK+ problem/bug?
Any help is appreciated. GTK+ version: 1.2.2

Thanks,

Ullrich
