Hi Michael,

thanks for your report. You are right, there is a problem in the
current cumulus version. After the last changes in the list trees I
had no time to make a deeper test. I found out, that your problem
occurs, if there are no waypoint and no airfield lists are available.
I tried to fix the problem and commit the change to subversion. In my
environment all is running fine now. See also my other comments in
your written text.

greetings Axel

The X11 build should now run again without a core dump.

What is the problem with the nmeaSimulator build? Please give my some
more information about your problems. I can build it in my environment
(Gentoo Linux and QT4.5.0 prerelease) without any problems.

I hope, your problems are solved now ...
