OK, thanks a lot!

Hi,

this is a known FOP bug. A bug report already exists:
https://issues.apache.org/bugzilla/show_bug.cgi?id=49837

Originally the bug was introduced by this patch:
https://issues.apache.org/bugzilla/show_bug.cgi?id=48071
http://svn.apache.org/viewvc?view=revision&revision=893238
I worked around by commenting some of the new code introduced by the patch but that's not a good solution. I attached my patch in case you want to use it anyway. 

Regards,
Matthias Reischenbacher

Hello list,

Doing some FO transformations, I get a strange exception. It happens
only to a few of my FO files and I cannot determine where this comes
from. This happens with FOP 0.95 and 1.0. Have anyone seen that before?
Thanks a lot if you can help!
