gvoice login error

My pygooglevoice 0.5 suddenly stopped working and if I run gvoice at the command line like
 # gvoice -b -e myname@gmail.com -p wtfpasswd call 18664254745 1CALLBKNUMBER 3
I got a error saying Login failed.

I found at this thread that it's probably due to recent changes in the Google voice web login interface. And after I have the following in the file /usr/lib/python2.7/site-packages/googlevoice/settings.py (the folder might be python2.6 depending on the python version installed), it works again and gvoice can dial out without any problems
