I'm working on a multiuser system with mercurial. I haven't been using the system lately, and today I wanted to start again, but mercurial refuses to work:

$ hg help
*** failed to import extension transplant from
mercurial_keyring =: [Errno 2] No such file or directory: '\nmercurial_keyring ='
** Unknown exception encountered with possibly-broken third-party extension hgflow
** which supports versions unknown of Mercurial.
** Please disable hgflow and try your action again.
** If that fixes the bug please report it to the extension author.
** Python 2.7.10 (default, May 26 2015, 04:16:29) [GCC 5.1.0]
** Mercurial Distributed SCM (version 3.4)
** Extensions loaded: color, largefiles, graphlog, hgk, strip, mq, rebase, record, shelve, hgflow, terse-status
Traceback (most recent call last):

    sys.exit((dispatch(request(sys.argv[1:])) or 0) & 255)

    origfn = getattr(container, funcname)
AttributeError: type object 'workingctx' has no attribute '_poststatus'

Mercurial works for all other users. My first observation was the usage of Python 2.7 instead of the default Python 3.4:

$ python --version
Python 3.4.3

Also removing the module from the global hgrc doesn't help. Then the error occurs for another module:

$ hg parent
** Unknown exception encountered with possibly-broken third-party extension hgflow

Same error message, same callstack.

Nothing in my env looks suspicious, there are no modules loaded, so I'm a little bit puzzled now.

Turns out that it is due to the now incompatible extension terse-status.
