Picking "All stations" by country causes NoneType exception

[AdamReid]

Got a chance to do some beta-testing of the RadioTime plugin and found this bug.

To reproduce:

Go to Internet Media -> TV -> MediaTime -> Countries, Pick a country (I tried Canada, Australia, Italy, South Africa) then select All Stations.

Expected result:

A list of all stations available in that country, or an indication that none are available

Current result:

Message titled "ERROR ENTERING A MENU" that reads:

"It was impossible to enter the menu 'All stations'.
Moovida was able to extract the following technical details that may help troubleshoot the issue:

'NoneType' object is unsubscriptable"

More information:

Running moovida from the command line gives the following backtrace when the error occurs:

I can reproduce with Italy

[Olivier Tilloy (osomon)]

I can reproduce with all countries I tested, although the error message is sometimes different: "No location nor uri parts provided".
