Unfortunately, this never should have been made a release; or at least should have been marked as a beta. There are several series issues. One of the forums has this:
people are having problems with the newest version of Stellarium. I
downloaded the 0.10.3 version and tested it out and it is a resource hog
and crashes when you zoom in/out quickly using the mouse scrollwheel.
Other people are having the same problem.
On the Stellarium site
there are links to previous releases of Stellarium. I prefer the 0.9.1
version which has never crashed on my system.
I found this one interesting, because I thought it might be Mac specific. I guess not. Also, is there a users mailing list, or just the developer list?
