Description of problem:
I tried to merge files by calling "git mergetool" (my merge tool is set to meld).

Version-Release number of selected component:
meld-3.14.0-2.fc23

Additional info:
reporter:       libreport-2.6.3
cmdline:        /usr/bin/python /usr/bin/meld --help
executable:     /usr/bin/meld
kernel:         4.3.3-303.fc23.x86_64
runlevel:       N 5
type:           Python
uid:            1000

Truncated backtrace:
meldapp.py:277:parse_args:UnboundLocalError: local variable 'args' referenced before assignment

Traceback (most recent call last):

    tab = self.parse_args(command_line)
  File "/usr/lib/python2.7/site-packages/meld/meldapp.py", line 277, in parse_args
