Hi Gaetan,

Sorry it took me so long to get to this, but I've been out of town for
the last three weeks at conferences. It's fixed, and the patch should
be in the next version of Sage (which is only a few days away). Credit
also goes to Willem Jan Palenstijn and Rob Bradshaw.

Definitely let me know if you run into any more troubles! The only
reason we hadn't hit this one before is that I'd never tried making a
Dirichlet character for such a large prime. :) But I'm very happy to
help with any bugs you hit. Also let me know if you run into anything
that's unbearably slow, and I'll be happy to look into it.
