Crashes upon use of dead keys - Mac OS X 10.10.5

[joel-magnusson]

Python instantly crashes, throwing NSRangeException, upon entering a dead key into one of the three text fields (Rep, Opp, Rev), when using Mac OS X 10.10.5. This issue seems to be fixed, but it also seems like Apple have yet to include the updated libraries in their shipped OS versions.

Options:

1. Force people to manually rebuild Tk locally (not really an option)
2. Create executables not requiring the correct local (default) libraries
3. Catch the exception, somehow?
4. Tell people to disable the use of dead keys on their Macs (seems to require a 3rd party program such as Ukulele)
5. Simply tell people to not press any dead keys.
