#18 Crash in options-controls-configure

[Anonymous]

From Yahoo Groups thread "Has this problem with RealFlight 2 Interlink Controller already been solved?"

Crash occurs at the moment "configure" is clicked.

Mandriva 2008 and 2.6.2.9 kernel as shown in dump. The Nvidia driver is the one that Mandriva bundles in -- I haven't touched it.
