gnuplot-py (1.8-14.fc20) is incompatible with Python 2.7. The Gnuplot modules attempts to raise string exceptions, like this: raise 'option %s is not supported' % (k,) This results in the following exception: TypeError: exceptions must be old-style classes or derived from BaseException, not str
Yes, it seems there are some places where it is raising str, instead of Errors.OptionError. I'll see if I can make a patch. Notice that this package is largely unmaintained upstream (last release ~ 2012)
