KDE konsole err msg:QDBusConnection: session D-Bus conn created b4 QCoreAppliction...

Hi,

I have now got three F16 x86_64 systems that do this every time I start another konsole session:

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

AFAIK, konsole does not actually misbehave, but it's annoying to have these errors displayed every time I launch a new konsole - which I do a lot. This happens when I start konsole from another konsole, xterm or a "terminal".

This is reproducable on these different hardware (all fully patched F16 x86_64 - 3.2.7-1.fc16.x86_64 #1 SMP Tue Feb 21 01:40:47 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux:
1 home-brew tower - fresh install
1 HP Compaq nc6400 laptop - fresh install
1 HP Pavillion DV6 - DVD upgrade from F14

All exhibit the same error messages.

Twice (and only twice), I have also seen messages like this:
kbuildsycoca4 running...
kbuildsycoca4(2086) KConfigGroup::readXdgListEntry: List entry Categories in "/usr/share/applications/kde4/bluedevil-network-panu.desktop" is not compliant with XDG standard (missing trailing semicolon).
kbuildsycoca4(2086) KConfigGroup::readXdgListEntry: List entry Categories in "/usr/share/applications/kde4/bluedevil-network-dun.desktop" is not compliant with XDG standard (missing trailing semicolon).
kbuildsycoca4(2086) KConfigGroup::readXdgListEntry: List entry Categories in "/usr/share/applications/fedora-release-notes.desktop" is not compliant with XDG standard (missing trailing semicolon).
"KConfigIni: In file /tmp/kde-root/kconf_updateET2089.tmp, line 1: " Invalid entry (missing '=')

I think I launched konsole as root both times I saw the above messages.

Nothing looked interesting in dmesg, but /var/log/messages has this:

Feb 26 20:49:26 fred dbus-daemon[922]: ** Message: D-Bus service launched with name: net.reactivated.Fprint
Feb 26 20:49:26 fred dbus-daemon[922]: ** Message: entering main loop
Feb 26 20:49:56 fred dbus-daemon[922]: ** Message: No devices in use, exit

Since I can reproduce this problem every time on 3 installations, I assume it's reproducable. Anyone know what's going on here - and, better yet, have a solution?

Tx

Bump.

Would it be possible for someone to at least confirm that they also see this problem? That is, launch a konsole from the command line - do you see the errors I see?

Tx

Tx for the info. I have seen that there are numerous circumstances that cause these same messages to be displayed. Would it be possible for you (or anyone) to just start a konsole, and then just run another konsole?

I also get these error messages with "amarok --debug" - and hundreds of other lines of output (as one would expect). These D-Bus messages are also displayed with just "amarok" (i.e., no "--debug" too).

Tx again...

Well, I'll confirm that warning messages like this pop up for me, too. Another fairly common one is something to do with the locale being created with a "fake component."

On the other hand, they seem to be innocuous. At a guess there is one or more subtle bugs (or race conditions) somewhere in the KDE / Qt library interface.

I just applied some updates - which I do every month, or so. The problem is fixed. That is, the messages when I launch konsole from another konsole. I have no idea which of the 100 or so packages fixed it though...
