The root cause for this is the same root cause for why snapcraft has started to fail to build snapcraft and is related to an old implementation we had in our original snapcraft where we set LD_LIBRARY_PATHs into the core snap, this is broken since last wednesday due to a libc6 update on xenial.
It is clear that the snapcraft implementation that is left over is wrong, and it is unfortunate that an update to libc6 would break this way, but there is this saying that weird things can happen when mixing libc6 and this is the effect we get to see.
There is a workaround for this if in a hurry, if not, a fix will come soon.
