Hydrogen crashing desktop when opening. F10

[Nigel Henry]

As synaptic has been repaired now by an update, I thought that I'd try 
installing something to check it out, so installed Hydrogen, and 
hydrogen-drumkits, which installed ok without any of the previous md5 
missmatch problems.

Anyway, I click on the Hydrogen icon, which opens a page showing info about 
Hydrogen, then close that page. Hydrogen's small splash screen is showing the 
Hydrogen tries to open, but instantly crashes the F10 desktop, and takes me 
to a login screen.


I've just tried it on F10's Gnome desktop, with the same result.

Anyway care to try Hydrogen, and say whether it works ok for them, or they are 
getting the same problem as I am?

Other graphical sound apps are working ok (ZynAddSubFX, MhWaveedit, etc).

Thanks.

Nigel.
