Getting a string index error

[paul-apacio]

I've managed to log in fine, however when querying for specific rows with:
fm.doFindQuery({'idno': ['2011.63',]})

I get this error:

File "/usr/local/lib/python2.7/site-packages/PyFileMaker/FMData.py", line 50, in FMData __slots__, __init_dict__, __old2new__, __new2old__ = key_dict( from_dict ) File "/usr/local/lib/python2.7/site-packages/PyFileMaker/FMData.py", line 26, in key_dict k = normalizeUnicode(key,'identifier') File "/usr/local/lib/python2.7/site-packages/PyFileMaker/UnicodeNormalizer.py", line 109, in normalizeUnicode if not res.strip('_')[0] in string.ascii_letters

This maybe due to the data from the database:

Any ideas?
