Comment(by mstreng):
Ok, so here's something that really puzzles me:
{{{
sage: P
*** Warning: precision too low for generators, not given.
Fractional ideal (49582667258207098257547477827105364096774*a +
402403512193607551973543413116828658131543)
sage: P
*** Warning: precision too low for generators, not given.
Fractional ideal (49582667258207098257547477827105364096774*a +
402403512193607551973543413116828658131543)
}}}
I get the warning twice, indicating that something isn't cached!
In fact, if I do
{{{
sage: trace('P.is_principal()')
}}}
twice, then I get the following each time:
{{{
-> 1068 self.__ideal_class_log = list(v[0])
}}}
So you're setting {{{self.__ideal_class_log}}}, but the next time, {{{if
not hasattr(self, "__ideal_class_log")}}} is False again!
