Comment 4 Bit Twister 2015-05-20 01:25:48 CEST

Just a junk file.

I have a go/nogo desktop_app_ck script which reads *.desktop files and runs the Exec= line.
Example: 
$ grep exe /usr/share/applications/kde4/bluedevil-wizard.desktop
Exec=bluedevil-wizard %U

%U indicates bluedevil-wizard wants a url file. Local files may either be passed as file: URLs or as file path.

You can run bluedevil-wizard without arguments and it still creates a kde crash.

Comment 5 Nicolas Lécureuil 2015-05-20 08:37:34 CEST

please install the debuginfos packages and provide the backtrace

Comment 6 Nicolas Lécureuil 2015-05-20 08:38:21 CEST

and  cat /home/bittwister/tmp/desktop_app_ck/desktop_app_ck.junk

I am just a dumb user. You need to be specific as to which rpms to install.
There is no debuginfos package.

> and  cat /home/bittwister/tmp/desktop_app_ck/desktop_app_ck.junk

Its just an empty file to prevent File not Found errors.

Comment 9 Nicolas Lécureuil 2015-05-20 14:13:41 CEST

why don't you simply do "bluedevil-wizard" on the terminal ?

Comment 10 Bit Twister 2015-05-20 16:56:06 CEST

If you look at Steps to Reproduce: I did. It also segfaults.

FYI:
$  cat /etc/sysconfig/desktop
DESKTOP=KDE4
DISPLAYMANAGER=kdm

Runlevel 3 under startx.


Some info from the KDE crash handler:

Comment 11 Samuel Verschelde 2015-05-20 17:32:46 CEST

Does the crash handler give you more information? (especially, the lines before #5).
