Google Earth on PCLOS is kind of in limbo at the moment.
If you do a search for it you will find that there have been two or three threads about it.
I don't remembered all the details but it is hardware specific among other things.
On my quad core Phenom machine with an ASUS motherboard it is working again after doing whatever it said in one of the threads. But, some functions do not work and if used will make it crash or hang.
I know that Tex is aware of the problem and when a stable version becomes available, we will have it.
In the mean time, just don't use the functions that cause problems.
I would list the ones that I have found but normally by the time I see the symptom, I don't remember what I was doing when it appeared and if I do remember, I won't by the time that I am in a position to write it down.
