Listening to a playlist I noticed librespot crashing on a certain song.
I can reproduce it everytime, now the strange thing is,
sometimes it will play.

I'm running librespot on volumio2 with the plugin from balbuze.
So when it crashes it restarts when after a crash I select the device again, it wil play...

I got the following error when running librespot from the command line with verbose output.
hope it does make sense.

@plietar commented on GitHub (Mar 6, 2018):

This seems to be a release build, so functions have been inlined and are missing from the stacktraces.

Could you rebuild librespot in debug mode (just omit the --release argument when calling cargo).

Thanks

@cortegedusage @plietar
The error is from my additions to get get metadata out via udp for Volumio.

thread '<unnamed>' panicked at 'index out of bounds: the len is 2 but the index is 2', /checkout/src/liballoc/vec.rs:1551:10

The error is because this track (7DtrCdyysCDj5BlVKcassv) doesn't have a 600x600 image that I am trying to access (at index 2).

Will make it more robust.

ah

@plietar I didn't realise the additions from @ashthespy weren't implemented in this repo.
Should I remove this thread?

@ashthespy Thanks for your quick reply. Looking forward for a fix,

and both thanks for your hard work, I'm a heavy user both at home and at work.
cheers

@cortegedusage I'd say yes, close it here, can track the issue either at the volumio plugin repo, or the fork.
