Ping.

Generally, it is best to open a ticket in Sage trac, so you can be sure 
the problem is going to be fixed. This is because as far as I know 
patches for GiNaC don't automatically propagate to Pynac.

Anyway, in this case you'll have to port these two patches to Pynac:

<http://www.ginac.de/ginac.git?p=ginac.git;a=commitdiff;h=293ff6f6fe>

Cheers
