Squeezelite crashing on Picoreplayer during podcasts

I am a very happy user of Picoreplayer on a Rasberry Pie with a Hifiberry DAC. Almost everything works fine ...

Except that when I try to play the podcasts from http://hearbeats.dk/podcasts, squeezelite on the Picreplayer crashes after a few minutes.

What can I do to pinpoint and maybe eliminate the problem?

Any help appreciated,
