List index out of range with ra0
I'm using RAlink device, Right now i'm at school with a lot of wifi spots with 802.1x authentication.
And i'm getting these results after a scan.
wifi -i ra0 scan

Hey! Thanks for the bug report. I'm in the middle of finals, but I think I could take a look at this after my tests.

Hi @jargij,
I have finally had some free time to work on this. I fixed the bug in 22c10be81fdc0354d8a4226331450bf713f2088c and have released a new version of wifi (https://pypi.python.org/pypi/wifi/0.3.2).
I'm really sorry that it took so long to get to. I have been travelling lately and just haven't had the time to get around to it. I hope it's not too late.
I'm going to go ahead and close this bug out. Please reopen it if you run into any more problems.
No change. Offending iwlist output:

Are you manually feeding the output of iwlist scan into the parser?
Does this happen from the CLI?
Yes, this time it was from manual feeding to get traceback output when I got IndexError from the application that uses wifi as library.
