Description Mathias Panzenböck 2010-03-13 00:04:20 UTC 
Application: krunner (0.1)
KDE Platform Version: 4.4.1 (KDE 4.4.1)
Qt Version: 4.6.2
Operating System: Linux 2.6.32.9-67.fc12.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
From time to time krunner hangs quite long (no cpu usage though) before it starts the application I wanted to launch. Sometimes this is followed by a crash.

The crash can be reproduced some of the time.

 -- Backtrace:
Application: Run Command Interface (krunner), signal: Segmentation fault
82	T_PSEUDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS)

Comment 2 Dario Andres 2010-03-20 15:09:06 UTC 
From bug 231196:
-- Information about the crash:
KDE had just finished strarting up, I pressed Alt+F2 to launch an application,
the krunner box appeared but crashed before I could type the application name.

From bug 227365:
-- Information about the crash:
krunner often hangs on me when I want to launch a program. This time it even
crashed.
I did just change the plasma theme (which caused kwin to crash - as usual) and
krunners theme wasn't changed completely. Maybe thats related?

From bug 228201:
-- Information about the crash:
i probobly run krunner but not using it, then i browse dolphin and i so crash
message at this same moment strigi finish indeksing files.

Fedora12 with kde-4.4.0 ant qt-4.6.2
Input the string "xscreensaver-command -exit" and pressed "return" and krunner
segv'ed

enabled (no strigi though)

We are also going to track similar bugs at bug 224102. Those bugs have an
invalid dbus connection pointer on the backtrace... (not really sure if that
makes a difference)

still happens in 4.4.2
i have to kill it via ctrl+alt+esc.
Comment 17 Jonathan Verner 2013-12-23 08:43:08 UTC 
The hang happens again in KDE 4.12 (didn't seem to happen in prior versions as much, if at all).
(Kubuntu packages, dbus version 1.4.18). When I attached dbug to the hanged process it gave
me the following (redacted) backtrace:
