Sorry, but apart from the implicit fact, that this problem is observed independently of the presence of AccountManagerPlugin there is no new information here over #8087.

yes, I seem to have forgotten to close the ticket myself. Error first occurred during repository resync which caused everything to fail, but setting

git_fs_encoding = latin1

in trac.ini fixed it.
