Comment 23 for bug 1842382

I suspect that usrmerge actually is the issue. config_GetLibDir tries to auto detect the location of the plugins by checking /proc/self/maps and finding the object from which config_GetLibDir is mapped. So, since that's coming from libvlccore, the prefix is now wrong (/lib vs /usr/lib). (I don't know why it doesn't get it right detects it as /vlc/plugins instead of /lib/x86-64-linux-gnu/vlc/plugins, but who knows what else might be wrong.)
