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. kib@ and kan@ are CCed as per avg@ suggestion. --=20 Alberto Villa, FreeBSD committer http://people.FreeBSD.org/~avilla
