On my Ubuntu 14.04 LTS system, RH 1.5.5 doesn't seem to be very 'stable' ;-).
I can often (but not always) make it crash just by resizing the window
It will sometimes crash when I try to connect or disconnect to/from my PrintrBot printer
It will regularly crash if I just leave it open on my desktop for a few minutes
It won't remember the new window size. If I resize, then close, then open, RH 1.5.5 goes back to the original size.
