Comment(by dimpase):

 Replying to [comment:45 jdemeyer]:

 > sage-5.0.beta7 doesn't do this on my machine, so it must be something
 with your setup.  Are you referring to vanilla sage-5.0.beta7 or did you
 install any extra packages?

 Sorry, I can't reproduce this either, there was a fly in my vanilla,
 apparently :)

 I tried Jason's suggestion to replace the twisted import with importing
 misc.fpickle, but it doesn't work:
 {{{

 when building sage spkg. Could it be due to fpickle being Cython? I don't
 know.
