Fedora 9 and fop

Hi all,

I have recently upgraded my computer to fedora 9 (was fedora core 4) and 
suddenly fop doesn't work anymore. The X server is running, but I also tried 
the -Djava.awt.headless=true trick, which didn't work either.

Whenever I try to render a page, I am getting this in the logfile:

building formatting object tree
[1]
[1]

And then fop hangs.

On other machines the output looks like this:

building formatting object tree
[1]
table-layout=auto is not supported, using fixed!
Last page-sequence produced 1 pages.
Parsing of document complete, stopping renderer
Initial heap size: 20749Kb
(): Current heap size: 19121Kb
Total memory used: -1627Kb
Memory use is indicative; no GC was performed
These figures should not be used comparatively
(): Total time used: 388ms
Pages rendered: 1
Avg render time: 388ms/page

This applies to JDK 1.6 and fop 0.20.5, but I guess newer versions as well, 
since they also require X support via Batik, no?

I am guessing that some X libraries weren't installed, is there any 
information which ones are actually needed?

Many thanks in advance,

Ulrich
