Duplicate of #7981. Please upgrade to the latest version of the plugin (Mercurial 1.1.2 is not that recent either - 1.3.1 is current).

[Christian Boos]

Actually it's not exactly the same backtrace as in #7981 or in #8274, so don't hesitate to reopen if you still have the problem with the latest version of the TracMercurial plugin (source:sandbox/mercurial-plugin-0.11 branch).
