Ok, this was a sucker to track down.
Destroying a GtkInvisible eventually results in it becoming unrealized and
it's widget->style to be detached. But gtk_invisible_realize doesn't
attach the style (it really doesn't need any frickin style), this makes
the widget style attach counter to decrease by one each time a
GtkInvisible is unrealized, and eventually the style will be destroyed
while there are still references to it.
Here is a patch that just attaches the style. This is a bit wasteful,
since it is not needed, but it is a simple way to fix the problem.
This bug is probably in Gtk+ 1.2.x too.
