dbus communication error with all KDE apps

I'm right now not able to run KDE applications (kate, marble, skrooge, ...) since they return "Bus error" and then exit.
On some applications, before that, for example Kate, this message is printed out:

QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.

I'm running XFCE through "exec ck-launch-session dbus-launch" and D-Bus is active; it's not a temporary error since persists after rebooting.

Re: dbus communication error with all KDE apps

I doubt the two error messages are related - despite Bus being in both names, they are referring to different things.  That dbus warning seems to be ubiquitous and harmless in KDE apps (according to the almighty google - no personal experience with KDE).  The Bus error is from a program trying to access memory that doesn't exist.

Are you running 64bit or 32?  Do you have apps built for the wrong architecture?

EDIT:
As a debugging step, I suspect the output of strace with one of the "Bus Error" producing apps will be helpful.  I'm still learning to read strace's properly, but that should have the needed info when someone more proficient checks on this thread.  If the output of strace is long, please be sure to link to it in pastebin or a similar site.

Re: dbus communication error with all KDE apps

I found what was the problem, rootfs was reported to be full even if I had more or less 500MiB free space... I cleaned the disk (freed-up ~600MiB) and now KDE applications run without problems (and as you thought the warning was not related to the bus error)
df output states:

Filesystem     1K-blocks      Used Available Use% Mounted on
rootfs          10980564   9795744    634324  94% /

according to that rootfs has 10980564 blocks but only 10430068 available...

PS: I have to clean a ton of unused packages
