Date: Fri, 1 Jun 2012 10:52:16 +0200

I also see crashes whose stack traces looks quite similar when doing
editing on non-unicode text.

This is from editing a pure ASCII file. The crash originates from a
call to CGStringGetLength below ns_findfonts as well. Head of the
system crash reporter text looks like this:
