Radiobrowser gives weird terminal dump without a force unload or crash

[kozross]

Is this a bug or a feature request?

Bug.

What Pext version are you running?

Pext v0.11.1-19-g4ca9d49 (according to pext --version)

What OS are you using? (e.g.: Ubuntu 16.04, Windows 10, macOS High Sierra)

Arch Linux.

If this is a bug:

What did you do to run into this bug, step-by-step?

1. Start Pext in the terminal and load radiobrowser
2. Start some music playin'
3. Go to 'By Most Tune-Ins' (I think - I don't exactly recall what triggered this)
4. Observe this lovely dump in your terminal

This did not force a module unload or crash Pext - music kept playing.

What did you expect would happen?

Terminal spew not occur, especially indicating out-of-range issues.

What actually happened?

See note above.

Is there anything else you would like to add?

No.
