Can someone verify this or is it my fault ( "$DIALOG" -e -p '{message="HALLO";}' )?

As I've mentioned previously, the simplest way to look at how to invoke Dialog is to look at the Ruby library ui.rb that wraps it.

In your case you need (at minimum) informativeText too, try

"$DIALOG" -e -p '{messageTitle="HALLO";informativeText=foo;}'
