[Cumulus] Segfault on Cumulus startup (X11 build from Dec. 5 snapshot)

[Michael Kinsner]

Hi,

I'm getting started with Cumulus, and am encountering a segfault shortly
after starting the program (an X11 build on a desktop).  I wanted to ask
about the current status of the X11 build before diving into this
further myself.

I'm running under Debian with qt4.4.3.tar.bz2 from the Cumulus download
area (also tried the package directly from Trolltech), and using the
December 5 source snapshot of Cumulus.  Cumulus builds and
installs fine using the Makefile.X11 (nmeaSimulator fails to compile, so
I removed its build and install rules from the Makefile), and QT
examples bundled with the standard QT development package run fine.

I've included a gdb trace below.  Should the X11 build be working at the
moment, or is it known to be broken?  Are there any suggestions to get
this working, or should I take a look myself?

Thanks,
Mike Kinsner
