Comment 3 Thierry Vignaud 2012-12-24 16:35:58 CET

please:
1) enable the core release debug medium
2) install the following packages: gdb kate-debug qt4-debug kdebase4-debug
3) run the "gdb -q kwrite"
4) type "run" in order to start kwrite from gdb
5) when it crashes, type "bt"

then paste the backtrace you got in some text file you'll attach to this bug report (please do NOT paste it directly as a comment as it would be mangled)

Comment 4 John Balcaen 2012-12-25 03:34:30 CET

kwrite is looking for a dbus session.
If you're switching to a root session you should use su - & then you'll be able to use kwrite as root.
Regarding the error noticed with the use of "su -", nothing happens here.

[root@localhost aranud87]# gedit /usr/share/gnome-shell/theme/gnome-shell.css

(gedit:22342): EggSMClient-WARNING **: Failed to connect to the session manager: None of the authentication protocols specified are supported


** (gedit:22342): WARNING **: Could not connect to session bus
[root@localhost aranud87]#

Comment 7 Arnaud Vacquier 2013-01-12 16:46:09 CET

but it is work fine with "su -" on gnome

Comment 8 Nicolas Lécureuil 2013-02-02 23:57:46 CET

does it work with su - on kde ?

Comment 9 Jeff Robins 2013-02-03 06:25:33 CET

I get the same errors, but I follow the instructions in the error, which are also in the bug report:

To circumvent this problem try the following command (with Linux and bash)
export $(dbus-launch)

It works just fine after I e=do the export.

Comment 11 Nicolas Lécureuil 2013-02-11 02:50:14 CET

so this is not a bug.

you must use su - to start kde apps as root.

Yup, you need another tweak/fix which I provided as a link in Comment 2.
