All I can tell you from this message is that some pattern was destroyed too often. For example, the following code would cause this message:

cairo_pattern_t *p = cairo_pattern_create_rgb(0, 0, 0);
cairo_pattern_destroy(p);
cairo_pattern_destroy(p);

Well, do not free a pattern twice. ;-)

I guess that somehow getting a backtrace would me imensely useful for debugging this.

Good luck,
Uli
