Description wendellspam 2010-05-24 14:33:34 UTC
Application: kwrite (4.4.2 (KDE 4.4.2))
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
It was started from bash within screen, first with a file to open ('.gitconfig'), then without any command-line options at all, and it crashed on open. It managed to write 'sock_file=/home/wendell/.kde/socket-wacky/kdeinit4__0' to the terminal first.

This seems to me to be rather serious... kwrite won't even run normally without any options.

The crash can be reproduced every time.

 -- Backtrace:
Application: KWrite (kwrite), signal: Aborted

It looks like your dbus is not working properly (so that this isn't a kwrite problem). What does "started from bash within screen" mean exactly? Is it that you logged in to KDE, opened konsole/xterm/whatever, created a screen session therein and tried to run kwrite? This should work, try running
within that bash to check your dbus (you can look for dbus-daemon processes running, too).

OTOH if your situation is something like "started a screen from within KDE, then detached the screen session and logged out from KDE and now reattached to the screen session", then that can't work because the bash within that screen has stale DBUS_SESSION_BUS_ADDRESS pointing to a dbus-daemon that is not there anymore (went down with the first KDE session). You'll have to update it (just copy the information from a brand-new bash shell).

For sure no kwrite problem.
Thanks for the explanation, hope it helped the user.
