bug#49985: bash-mesboot0: Inscrutable error in build phase

[Bengt Richter]

Just this disclaimer:
I am just a lurker interested in mes, not a mes developer or team member.
(I am trying to do some minimal stuff too, so I cloned the mes repo and pull 
once
in a while to see what's going on :)

Sorry for any implication that I really know anything about mes ;/
