Downgrading only libvlc5 was not enough to reproduce, and downgrading
libblccore8 forced me to downgrade also vlc-data and vlc-plugin-pulse.
vlc -vvv output attached. I installed vlc-dbg version 2.2.1-3 (not
2.2.0~rc2-2+deb8u1) since that's the one the dependencies let me
install.
Here is the backtrace:
