Hello,
after I had noticed that FlightGear 0.9.5 (which comes with Debian sid)
provides support for my Saitek Cyborg Evo, I wanted to use this. But
because it is detected as "Saitek Cyborg USB Stick" (it is an Evo,
though), I modified the name in the respective XML file. But now it
SIGSEGVs. I recompiled my Debian package with debugging symbols and
asked GDB for a backtrace:

I hope this will help you.
I am afraid I am absolutely unfamiliar with the FlightGear internals.
Please ask me if you need further information.
SÃren
