Thanks.

It seems that your cairo XCB surface is destroyed twice.
It may be caused by Ruby's sweep (in GC) timing. Ruby script
can't control object order to be swept.


It seems that your script was finished by exception.
Could you confirm that your script raises any exception?

For example:

---
# ...

begin
  Gtk.main
rescue Exception
  puts "#{$!.class}: #{$!}"
  puts $@
end
---


Thanks,
