PPT filter fixed

[Joe Shaw <joeshaw novell com>]

Hey,

Varadhan has fixed the Powerpoint filter so that certain properties
don't trip it up and break indexing.  Hooray!

The bad news is that it also required a gsf-sharp release, and that
release (0.5) is now required to build Beagle.  Boo!

Those of you blessed with nobility and fortunate enough to be running
SUSE Linux 10.0 can get a package here:

        http://primates.ximian.com/~joe/gsf-sharp-0.5-1.i586.rpm
        
and the rest of you peasants can get the tarball:

        http://primates.ximian.com/~joe/gsf-sharp-0.5.tar.gz
        
Enjoy.

Joe
