This reminds me the threads
http://groups.google.com/group/sage-devel/browse_thread/thread/863e59ba164590c5/e29c67ce1230f27d
or
http://groups.google.com/group/sage-support/browse_thread/thread/abb492807b52973f/8737fbb78f1ed4e5
In other words:
Is Maxima involved in this computation?
If yes, then it might be related with ticket
http://trac.sagemath.org/sage_trac/ticket/4731
Is someone working on this ticket?
Cheers,
Simon
