Segfault in driver while launching controller

[schornakj]

Saw this crash in the logs for one of the Skills Center systems, apparently from when it was first launching the drivers after startup:

@schornakj do you have any version information?

[schornakj]

@moriarty this happened with the version of the package that's shipped with MoveIt Studio 1.11.4.
