pgpy.errors.PGPError: bytearray index out of range

[sharmaavi1996]

Recently have started seeing this issue come up and was wondering if something has changed to cause this. We have not changed anything on our end. We are attempting to load public keys in .asc format and seeing this error with various different valid gpg public keys:

PGPy version: v0.6.0
