Absolutely, this can't be the fix.  But when I run with valgrind with
and without the above change, nothing obvious about uninitialized
memory pops up.  However, there are some messages related to
fontconfig (I think) in both cases.  I'll check again and try to send
details later.

Just to add one more test:  this "fix" works on fedora 14, and I am sure,
on other Fedora releases.  It is obviously important to discover why this
has the effect that it does.  The real problem likely has (not good) effects
elsewhere.  Sadly, I do not really know where to start to help with this.
Very mysterious.

The fontconfig item may be relevant.  I notice when I run the legend test
without the "fix"  the plot window "flickers" which could suggest that
the legend is being drawn, but without the text which got lost due to
a font error.  Pure speculation on my part.
