--- Comment #4 from Uli Schlachter <psychon at znc.in> ---
Being too slow to read comments, I tested with gnumeric. Since I had no
starting point, I used something ancient (I think it was 1.8). The problem is
reproducible. Git bisect points fingers at:

$ git bisect bad
99fa5ff6c211b96326484f80fe91ead0860c3a23 is the first bad commit
commit 99fa5ff6c211b96326484f80fe91ead0860c3a23
Author: Chris Wilson <chris at chris-wilson.co.uk>
Date:   Sat Aug 13 20:07:57 2011 +0100

    snapshot: Defer acquisition

    Fixes 'xlib-expose-event' but triggers an infinite loop in self-copy.

So that it doesn't get lost, here is the bisect log (all the skips are due to
cairo-debug.c:37:41: fatal error: cairo-image-surface-private.h: No such file
