I digged into that deeper with the sources...
start_kdeinit_wrapper -> start_kdeinit -> kdeinit
is (on non-Linux) just an execvp(2) chain of the above three programs; on
FreeBSD it would not even be necessary because non of them runs with
setuid on execution.

As mentioned, the three programs
/usr/local/bin/start_kdeinit_wrapper
/usr/local/bin/start_kdeinit
/usr/local/bin/kdeinit
have been compiled on -CURRENT r197801 and have been untouched and
working since October, 16. On October 30, I compiled in addition the
port x11/kde4, which does not touch the above programs and also not the
shared libs used by them;

after the installation of x11/kde4 the start_kdeinit_wrapper now aborts:

$ /usr/local/bin/start_kdeinit_wrapper
Abort trap: 6

it does not abort when you set

# sysctl security.bsd.map_at_zero=1
security.bsd.map_at_zero: 0 -> 1

I think that security.bsd.map_at_zero was already 0 before compiling
x11/kde4, i.e. no part of KDE4 changed this sysctl value; so it remains
open, what caused this effect, but at least it is working again;

Thx
