Back to Simon, autostart maintainer is null@kde.org. :-(

Do you have yet this crash ?
I can't have it.
Which qt version do you use ?

I'm still able to reproduce it with the same testcase and the same backtrace, yes.

(kdebase rev. 832593)

Just to refresh the bt :

systemsettings(17000)/kdeui (KIconLoader) KIconLoader::loadIcon: No such icon "kmldonkey"
systemsettings: /media/kde/src/KDE/kdelibs/kio/kfile/kpropertiesdialog.cpp:273: KPropertiesDialog::KPropertiesDialog(const KUrl&, const KUrl&, const QString&, QWidget*):  l'assertion « !d->m_singleUrl.isEmpty() » a échoué.

And same question: Which is your qt version ?
(we have a patch in qt-copy which fixes this error. Do you have it ?)

Last note : dragon doesn't seem to make it crash anymore.
Kmldonkey, Kimagemapeditor or Kontact do.

And yes, qt-copy is up-to-date and patched here. Which patch is it ? I can check if there was a problem while patching.

The qurl patch was 0217-qurl-isempty-regression.diff (r782275, in March). This fix is part of Qt nowadays (including qt-copy).

Maybe this assert is because of a url that -is- really empty?

*** Bug 168063 has been marked as a duplicate of this bug. ***

kubuntu 8.04 kde 4.1.0 - still happens (adding kontact)

*** Bug 168408 has been marked as a duplicate of this bug. ***

Just confirming I have this same problem trying to add Konqueror and Kontact. Happy to do any tests and traces etc if needed.

Kubuntu and KDE 4.1, weekly foxes.

I also have this, with trace info below (I am using archlinux kdemod 4.1.2):

I have similar bug with KDE 4.1.2.  when adding a program to autostart, I cannot pick application from the startmenu tree -- this will crash systemsettings. But if I type the path of an application in the edit box directly it does NOT crash.

I couldn't reproduce the crash with a 4.1.81 snapshot. 

@commenters, please check and report if you still experience this crash.

Crashes in trunk.

Definitely fixed for me now, KDE 4.1.3

Here using:

Qt: 4.4.3 + qt-copy-patches-910240
KDE: 4.2.60 (KDE 4.2.60 (KDE 4.3 >= 20090116))
kdelibs svn rev. 915739 / kdebase svn rev. 915763
on ArchLinux i686 - Kernel 2.6.28.1

I can't reproduce this crash

Can anyone still reproduce this bug with a recent KDE (4.1.4 / 4.2beta2 / 4.2rc1 / 4.2.0 / 4.2svn / 4.3svn) ? Thanks :)

Tested with KDE 4.2RC2 (Kubuntu 8.10). Works fine, no problems.

Let's close it, I tested with trunk, reported to be working with 4.2RC2, no need to keep it open.
