After getting the snapcraft snap automatically refreshed to the 1503 revision (2.42) I am having this problem when trying to execute "snapcraft", "snapcraft clean" or just "snapcraft --version":
Traceback (most recent call last):

I'm trying to do it in an armhf using Trusty. I reverted to the previous version (2.41 - rev 1427) and everything works as usual.
I have almost complete certainty that this is related to a missing armhf key in our library searcher for ctypes.
