In short, rebuild python 2.7.13 and this problem will be fixed.  Remove
your $HOME/.config/zim and $HOME/.cache/zim.  Start zim as normal.

The issue lies in the python multiprocessing module.  Zim is unable to
start up because it cannot import the required module.

The following will return the import error:

> python -c "from _multiprocessing import SemLock"

This problem can be seen if you run zim in debug mode during the first
launch of the application.  See attached log.

Thanks,
