I can reproduce this bug on any of the systems (OS X PowerPC/Intel, Linux x86,
Windows XP).

It is a statistical bug, happening randomly. To repeat:

1. Get "TexasFlag" project from Google pages or subversion (recommended):

   http://akauppi.googlepages.com/TX-20081127.tgz
   svn co svn://slugak.dyndns.org/public/2009/TX

2. "make run"

4. There should be a Texas flag drawn in a GUI window. 

5. Start resizing the window by dragging from its corner.  Within a second or
so, you'd get a crash.

On OS X, it may be beneficial to start the utility like (gives you the console
log):

$ TexasFlag.app/Contents/MacOS/TexasFlag 
Assertion failed: (CAIRO_REFERENCE_COUNT_HAS_REFERENCE (&cr->ref_count)),
function cairo_destroy, file cairo.c, line 218.

Running Cairo 1.8.4 on all the systems.
