Ah, that revealed something more interesting:
9568 execve("/lib/dbus-1.0/dbus-daemon-launch-helper",
["/lib/dbus-1.0/dbus-daemon-launch-helper",
[...]
9568 <... execve resumed> ) = -1 EACCES (Permission denied)
So apparently /lib/dbus-1.0/dbus-daemon-launch-helper isn't executable
for the user "messagebus". That' s a bit weird, since in comment 3 the
actual program permissions are correct, and since (I presume) you ran
"ls" as normal user the directory permissions should be okay, too.
However, please check/give me the output of
ls -ld /lib
ls -ld /lib/dbus-1.0
They should both be drwxr-xr-x root:root. Also, please try to manually
run it as user messagebus:
sudo -u messagebus /lib/dbus-1.0/dbus-daemon-launch-helper
What's the output?
Let's also check integrity of the binary:
(cd /; md5sum -c /var/lib/dpkg/info/dbus.md5sums )
Any line which doesn't say "Ok"?
Finally, do you get anything interesting in dmesg if you do this? If you
aren't sure, and it's just technobabble to you, please attach
/var/log/kern.log after those tests.
Thanks!
