Comment 54 for bug 482993

Another note: the environment contains 'VERSIONER_PYTHON_VERSION': '2.5'
which tells that either
a) the test was run with a patched version of the official Inkscape.app (as mentioned in comment #33 and earlier): this of course would have made the extension work even without a user-installed 32bit Python version, or
b) the shell environment of this computer has this variable set globally or in your account specifically (e.g. in one of the shell startup files or in ~/.MacOSX/environment.plist).

It also confirms that only Apple's Python knows about the specific versioner mechanism [1] and the variable is ignored by other python builds (comment #35).

For further tests please use the original Inkscape.app, or document any patches you had applied before running the tests.
