Crash on exit

Navit crashes when I exit it.

Backtrace:

This may also be relevant. It is printed out before the crash

navit: fccache.c:512: FcCacheFini?: Assertion `fcCacheChains[i] == ((void *)0)' failed. Aborted (core dumped)

This is caused by a call to FcFini? in the quesoglc library. It only seems to occur if the sdl gui is built, but not enabled in navit config. My testing shows the following:

• --disable-gui-sdl then configure gtk gui in navit.xml => no crash
• --disable-gui-sdl then configure sdl gui in navit.xml => Navit does not run (as expected - no gui)
• --enable-gui-sdl then configure gtk gui in navit.xml => crash
• --enable-gui-sdl then configure sdl gui in navit.xml => no crash

I suggest, as a work-around, configuring without sdl if you do not intend to use it (you'll need to do a make clean as well, to remove the old opengl libs)

cegui support will probably be dropped.
