Bug 339094

IMHO is that a frameworks issue, I looked at it a bit, and this is the reason I traced and wrote to frameworks-devel:

Hi,

for Kate, the startup info doesn't work atm in frameworks.

If you launch dolphin KF5 version and open one file => fine,
second file => dolphin blocks and startup info doesn't happen.

If you look at the logs, you see:

 (1975)/(default) KXMessages::broadcastMessageX: KXMessages used on non-X11 platform! This is an application bug.

Which is on my machine the kdeinit5 process that can't use KXMessages as the guard
there seems not to work (there is a isX11....() check).

Might it be, that this check in QX11Info needs a application instance which is not there in the kdeinit5 process?

Greetings
Christoph 

Perhaps thats wrong, but thats all I see ATM.

I also see this bug with KF5.5, plasma 5.1.2 and dolphin-frameworks-git...

Distro: Arch x64
KDE: 4.14.4 with parts of KF5 5.6.0

[tomasz@arch ~]$ pacman -Q|grep kdelib
kdelibs 4.14.4-1
kdelibs4support 5.6.0-1

FS#43513 [kdebase-dolphin] [kate] kdeinit could not launch '/usr/bin/kate'

[tomasz@arch ~]$ pacman -Q|grep kate

Steps:
Open Dolphin
Open in Kate any text File. 
Switch to Dolhin Window and try any action. For example open next tab.
Window freeze. After some time content is not visible:

AFTER close kate window I see prompt:

AFTER close prompt Dolphin window is good and working fine again:

Hey, I found a walk-around.
Remove "-b" option of kate with kmenuedit will prevent dolphin from hanging up, although it will keep telling you "KDEInit could not launch '/usr/bin/kate'" (which is not true).

Removing X-DBUS-StartupType=Multi from the .desktop file fixes this for me. Can this be implemented as a workaround while this is fixed upstream? This is a really bad bug IMO, it makes kate useless for any advanced use.
  Comment by Tomasz (FadeMind) - Saturday, 24 January 2015, 19:49 GMT+1 — Edit
One more issue:
looping loading animation on kate icon after open several files. This feature can be disabe by adding value:

StartupNotify=false

in to the file /usr/share/applications/org.kde.kate.desktop
I confirm:
Disabling/removing X-DBUS-StartupType=Multi line in org.kde.kate.desktop file fixed issue kdeinit could not launch '/usr/bin/kate'

Great. Please report those informations in the upstream bug report.

Created attachment 90643 [details]
Register with dbus to wake up KRun, and unregister then

Documentation of KToolInvocation (called by KRun when click a file in dolphin) said "Multi" means "Always start a new service, wait until the service has registered with D-Bus". But when the second text file is opened, kate just starts a QApplication and waits, without registering with DBus.
In KDE 4, the second instance of kate launchs an empty KApplication to do this job, but the author said "it's too bad" to register a service. Maybe we can register to make KService happy and unregister at once.
Another problem is that the kate icon will jump quite a few seconds after clicking the second file. I thought the reason was KStartupInfo::appStarted() not called as it requires Q_WS_X11 macro, which is not defined in Qt 5. But the bug still exists after I fixed this.

FWIW, the patch fixes the problem here!

@Christoph,
i guess Liu should open a review request @ reviewboard.kde.org ? or can be reviewed this way?

*** Bug 343613 has been marked as a duplicate of this bug. ***

err why got this bug assigned to me?

Look at Comment 1, perhaps I am wrong, but KWindowSystem seems to have some problem in KXMessages sending the events. But perhaps I am wrong.

please check again. The warning printed in comment #1 got fixed in KWindowSystem quite some time ago. See http://commits.kde.org/kwindowsystem/837f1ccc0af5b53dcd394d5cce535ee54a857933
