I do not think it was that commit, as I found the offending commit:
c7b2b539802eaa3f969e212c98eb671a1a75e9f3

This is the commit that adds mumimu to gnu/packages/mail.scm, as well as
to the inputs of mumi. Reverting this commit (at least) solves the issue
I had in the first mail.

Could it be that the reference to guile-email in the version field of
mumimu created this issue?
