Simulator 4.0.7 does not seem to work on Linux

Running Linux SDK 4.0.7 (in Docker):

- monkeyc works OK

- simulator launches OK

- monkeydo launches OK

- BUT nothing appears in the Simulator (which keeps displaying the Garmin blue triangle)

monkeydo-ing the binary compiled above in the SDK 4.0.6 does work (application launches and behaves just fine)
