Gus has been away for a while, but before disappearing he found a
workaround to be building devel/dbus-qt4 with -fno-use-cxa-atexit. So
I had a look around, and found this NetBSD bug report:
http://www.archivum.info/fa.netbsd.bugs/2007-12/00070/lib-37654-libc's-atex=
it_mutex-should-be-fully-recursive.html

Since qdbus crashes after exit(3) here too, that might be an
explanation. Or, at least, something related.
