Mercurial crashes because of the qct extension - which I haven't enabled

On one of my Mercurial repositories, which used to work, when I run hg status I get:

** Unknown exception encountered with possibly-broken third-party extension qct
** which supports versions unknown of Mercurial.
** Please disable qct and try your action again.
** If that fixes the bug please report it to the extension author.
** Python 2.7.12 (default, Sep 29 2016, 13:30:34) [GCC 6.2.1 20160916 (Red Hat 6.2.1-2)]
** Mercurial Distributed SCM (version 3.7.3)
** Extensions loaded: qct, color, pager, extdiff, hgk, graphlog, hggit

Now, I haven't enabled a qct extension, and I can't find it in my .hgrc nor in the .hg/hgrc in the repository. What's going on here? How can I fix/circumvent this problem?

Actually are you sure ? You haven't shared what distribution you are using, for example in Debian qct is its own package. I just purged it as I also got similar error.

There are possible system-wide config files. From hg help hgrc:

On Unix, the following files are consulted:

  • "/.hg/hgrc" (per-repository)
  • "$HOME/.hgrc" (per-user)
  • "/etc/mercurial/hgrc" (per-installation)
  • "/etc/mercurial/hgrc.d/*.rc" (per-installation)
  • "/etc/mercurial/hgrc" (per-system)
  • "/etc/mercurial/hgrc.d/*.rc" (per-system)
  • "/default.d/*.rc" (defaults)

As user config files override the system-wide config files you can disable it locally. Quote from https://www.mercurial-scm.org/wiki/UsingExtensions :

To explicitly disable an extension enabled in an hgrc of broader scope, prepend its path with !:

[extensions]

# disabling extension bar residing in /path/to/extension/bar.py

bar = !/path/to/extension/bar.py

# ditto, but no path was supplied for extension baz

baz = !
