Problems with gdk_colormap_unref/gdk_visual_init/purify

[julian gosnell nomura co uk]

I have been playing with a little program which adds and deletes large numbers
 of widgets to/from a gtknotebook (I've tried a vbox as well).

After about 20/30 add/deletes I get a segv - it looks like gdk_colormap_unref
 has been called (for the first time) with a trashed pointer.

Aha - I think, time to get out purify and find out where the memory is being
 overwritten. But every purify-ed binary I produce hangs in gdk_visual_init
 (apparently on the first switch statement - no matter what I do I cannot get
 past this).

I am running gtk+-1.0.1, gcc-2.7.3.2/2.8.1, purify 4.0.1/4.1 on Solari 2.5

Has anyone else experienced problems with purify ?

Has anyone else come across this gdk_colormap_unref problem ?

Any help would be appreciated - I'm at my wits end.
