[cairo] cairo-xlib-surface.c:402: _swap_ximage_to_native: Assertion `NOT_REACHED' failed.

[Erik Ohrnberger]

Dear Cairo users,
	I've been struggling with a Gentoo system where the error message
above is causing all the program that rely on cairo, like gtkmm based
programs, to core out.

	I was wondering if there were any known issues of configuration
changes that could be applied to remove this issue.

	Thanks,
		Erik.
