Possible bug on Linux when running an MPS instance from MPS

If I try to start a new MPS instance from MPS I get the long error reported below.
Adding the following JVM parameter to the run configuration, magically, fix the problem:
    "-cp <intellij-community github clone>/community-resources/src"

Bye,
