jsonpickle fails autopkgtests with pandas 3.0 (in experimental):

https://ci.debian.net/packages/j/jsonpickle/unstable/amd64/73190624/

It looks like it's checking dtypes (pandas assert_frame_equal etc do
that by default), and not expecting the new string dtype.

Probably better idea: upstream's fix, which looks like it actually does
preserve these dtypes.

(This hasn't been in a release yet, i.e. upgrading to 4.1.2 won't help
with this, though it's plausibly a good idea more generally.)
