Skipping linenumbers yields TypeError

lingua 4.9 python 3.4.3

Create a file foo.py:

_ = lambda a: a

FOOS = (
   _('one'),
   _('two')
)

Run pot-create:

$ pot-create -o bla.pot --keyword "_" foo.py --no-linenumbers once:

a bla.pot is created correctly and contains 'one' and 'two' msgids. Now run pot-create again:

$ pot-create -o bla.pot --keyword "_" foo.py --no-linenumbers

Without --no-linenumbers option pot-create works as expected.

Just checked - the behavior was introduced in 4.9, 4.8.1 works fine...

Sorry, my bad, it was fixed in 4.10 :)
