OpenSuSE 11.1

The Gnumeric [svn HEAD] test suite's pdf generation test is unhappy.
It shows memory access violations in Cairo.  Sample below, full log
to follow.

This all worked fine with whatever versions that OpenSuSE 11.0 shipped.
It also does not look like a problem that Gnumeric could have easily
caused by itself.
