Not sure whether this is a 100% issue of the MacOS build, but I have seen such strange behaviour only on El Capitan by now.

When trying to use Mercurial from GeanyVC I'm getting a backtrace

Mercurial is installed via brew and is working from normal shell. As well as e.g. git — also installed via brew — is working.
