Points to dash - since the update. With this information I found more on
the Ubuntu wiki. Will try the recommendation given there to alter the
first line of the start script to #!/bin/bash.

When I work in a terminal, I'm using bash (version 3.1.17(1)-release).

Thank you for your help, this really sounds promising.
