Hi Werner:

Thanks very much for running that test.

If you do exactly the same thing with lasi-1.1.0 do you get the same
segfault with your current pango/cairo stack?

What I am concerned with is whether this is a regression due to our recent
changes or something that was present in lasi-1.1.0 as well.

If it is a regression can you bisect it (manually or with svn-bisect) to
find which of our recent commits caused the issue?
