pmag_gui puts in extra lines at the end of tables when editing

[ltauxe]

What command was run:

pmag_gui.py

What happened:

tried editing table button 3 from a data set that passed validation. after saving the edited files there was an extra, erroneous, line at the end of the table and the contribution failed validation.

What I expected to happen:

I expected the edited file to pass validation as it had before minor editing.

Data file(s):

run 'unpack' from pmag_gui.py then try editing a column and saving it:
magic_contribution_19534.txt

Screenshot(s):

PmagPy version:
pmagpy-4.2.102

actually - it is the OSX standalone version that does this. version 4.2.102 doesn't do the editing at all! it hangs after choosing column headers with this error:
