AttributeError: 'tuple' object has no attribute 'rfind'

[jcea]

I am using Mercurial 3.4.

I have "hggit" activated globally in my profile.

When I do "hg up -r tip" in a particular mercurial repository (NOT git backed, a pure mercurial repository) I get this traceback:

** Unknown exception encountered with possibly-broken third-party extension zipdoc
** which supports versions unknown of Mercurial.
** Please disable zipdoc and try your action again.
** If that fixes the bug please report it to the extension author.
** Python 2.7.9 (default, Mar  1 2015, 03:30:17) [GCC 4.8.1]
** Mercurial Distributed SCM (version 3.4)
** Extensions loaded: strip, mq, convert, graphlog, record, rebase, transplant, largefiles, churn, hggit, shelve, zipdoc

Disabling zipdoc extension doesn't solve the issue.

Disabling hg-git extension DOES solve the issue.

I have other repositories not experimenting this issue.

This directory doesn't have a ".git" neither a ".hgignore" file.
