(apologies for the cross-post -- but it now seems to be a pango
problem rather than gtk+)

Update: I made a simple test case with an app that just contains a
GtkEntry widget which exhibits this problem.  I rebuilt gtk+ with some
debug print statements and determined that in gtk_entry_size_request()
it was setting a height of 4115.

It gets 4115 because pango_font_metrics_get_descent() is returning
4194304!  I'm not too familiar with pango, but this would appear to be
a much larger than normal value.

I'll continue investigating this to figure out what's going wrong in
my spare time, but any advice would be appreciated.

Thanks,
