Taskcoach doesn't start - Possible python problem?

[WilliamColls]

I am trying get taskcoach up and running. Installed from the repository with out problems. However, when I try to run it from the Application launcher, it appears to start, and then immediately disappears from the task bar. If go to the process table it shows up there. If I try to start it from a terminal I get a series of error messages:

/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:40: Warning: g_boxed_type_register_static: assertion 'g_type_from_name (name) == 0' failed

I am not a python user, so not sure where i should be starting to look for the problem, or even if I would recognise it if knew where start.
Installed version of python:

Python 2.7.15rc1 (default, Nov 12 2018, 14:31:15)
[GCC 7.3.0] on linux2

Any help will be greatly appreciated.

Thank you for you time.

William.
