VUnit GHDL docker image crash

I am trying to run my simulation on the ghdl:vunit/llvm-master docker image but I am getting this error.

Traceback (most recent call last):

The simulation runs fine if I use hdlc/sim:osvb image. They ship the same VUnit version, but a different release of GHDL (v3.0.0-540 for the ghdl one, v3.0.0-340 for the hdlc one).
