(mistakenly) adding empty custom station creates stutter in playback

[axelsimon]

Hi,
first of all thanks for a great add-on. It really is one of the higher quality add-ons on Kodi I know of.

OS: OSMC 2017.08-1
kernel: Linux osmc 4.9.29-9-osmc #1 SMP PREEMPT Sat Jul 29 01:44:42 UTC 2017 armv7l GNU/Linux
hardware: Raspberry Pi 2

Here is the issue I ran into. I had a radio playing and while playing around with the Kore remote app, I went into the My Stations and tried to add a radio, using the Add custom radio. I realised this was to add an entirely custom one, so as I didn't have a specific name/thumbnail/URL combination to enter, I just clicked "done" on each text entry.
As soon as I clicked "done" without entering text on the third screen (URL entry), the playback started to stutter, making it impossible to listen to.
I then stopped playback, started it back up and it played fine.

Here is the relevant part of the log:

The stuttering has reappeared a few time since, with the 20:19:37.893 T:1456993264 ERROR: CWebServer[80]: failed to handle HTTP request for /image/ line reappearing in the logs.

Hope this is reproducible on your end (or alternatively, that no one runs into this weird condition).

Cheers
