Comment 4 basz 2015-02-01 21:17:58 UTC

got the same problem for a very long time now (debian/testing). my system (currently) is:

Application: akregator (4.14.1)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 8.0 (jessie)

out of interesting stuff, when starting akregator on a console it shows:

QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
QSystemTrayIcon::setVisible: No Icon set


and then, when closing it it crashes:

Object::disconnect: Unexpected null parameter
Object::disconnect: Unexpected null parameter
akregator(25169)/kdecore (KConfigSkeleton) KCoreConfigSkeleton::writeConfig:
akregator(25169)/kdecore (KConfigSkeleton) KCoreConfigSkeleton::writeConfig:

KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit

Comment 5 cricketc 2015-02-09 19:24:16 UTC

I don't know if this is the same issue or not, but Akregator (4.14.3) regularly crashes for me when I logout of the KDE session.

Comment 6 Pali Rohár 2015-03-01 11:36:50 UTC

Confirmed, same problem with same backtrace. Also it crash on KDE logout.
