Hi, I got an assertion failure when running the "challenge4.rb" from http://hackety.org/2008/06/12/martinDemellosGooeyChallenge.html
The shell output looks like this: abhi...@azad:~/play/shoes$ shoes challenge4.rb shoes-bin: /build/buildd-cairo_1.8.6-2-i386-nK2POA/cairo-1.8.6/src/cairo.c:218: cairo_destroy: Assertion ((*&(&cr->ref_count)->ref_count) > 0)' failed. Aborted abhi...@azad:~/play/shoes$ It crashes as soon as the mouse pointer enters any of the buttons and leaves. I am running latest shoes from git's hub with ruby1.8. My computer run Debian testing/unstable, with libcairo2 1.8.6-2. BTW the example does not arrange the buttons as advertised, but I suppose thats a smaller problem in comparison. -Abhijit
