Comment 2 for bug 522520

When I search for the ISS, and hit enter, the screen goes black and I got what you see in the screenshot. Obviously, there is a problem with all this NaN value here and there.

if I try to move stellarium screen i get always black after such a search. Ctrl-Shift Z gives in satellites tab a list of all visible satellites. I can see the TLE of IIS at the bottom of the window. (i can't take a screenshot of this dialog)
