GUI can die if I click "Run" too soon after a previous action completed

[sea-bass]

If I click the "Run" button on a new skill immediately after another one completes, the SkiROS2 GUI dies.

The error:

[rqt_gui-3] Traceback (most recent call last):

Thanks for reporting this. I think I should merge RobotLabLTH/skiros2_std_lib#15 that should cure this one as well and will make everything more responsive. I was a bit hesitant first so shortly before the workshop since it's new, but it should tackle a couple of things
