Oops - I should have read the earlier part of the this bug better. :-/ gpodder's mtp support appears to have been commented out for a long time. FWIW, the MTP support in gvfs doesn't appear to work as an alternative for me - get an error about the filesystem not being local.
I do actually have a version of the package ported to Python 3, if that would be useful. -- Jelmer Vernooij <jel...@jelmer.uk> PGP Key: https://www.jelmer.uk/D729A457.asc
