[cairo] Fatal IO error 104 (Connection reset by peer) on show_text

[Jake Brownson]

Found the problem last night, filed bug:
https://bugs.freedesktop.org/show_bug.cgi?id=13266

To summarize the font size was too large in relation to the window. X
apparently didn't like that and the error didn't get handled so we
just crashed.
