Reported using DrKonqi 1092631 1 kaddi.bug 2011-03-02 14:16:23 +0000 Hi, I just noticed an additional information of which I do not know how useful it is. The crashed plasma-desktop session had been started from command line and hence there has been some output in the command line, I noticed just now: QMenu* DBusMenuImporterPrivate::menuForId(int) const: Condition failed: action void DBusMenuImporter::GetChildrenCallback(int, QDBusPendingCallWatcher*): Condition failed: menu QMenu* DBusMenuImporterPrivate::menuForId(int) const: Condition failed: action void DBusMenuImporter::GetChildrenCallback(int, QDBusPendingCallWatcher*): Condition failed: menu KCrash: Attempting to start /usr/bin/plasma-desktop from kdeinit sock_file=/home/kaddi/.kde/socket-homer/kdeinit4__0 KCrash: Application 'plasma-desktop' crashing... KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit sock_file=/home/kaddi/.kde/socket-homer/kdeinit4__0 QSocketNotifier: Invalid socket 14 and type 'Read', disabling... The KCrash entries are from the bug-collector with which I submitted the report, the QMenu-messages may be relevant to the crash. regards kaddi 1124879 2 asraniel 2011-05-29 17:35:08 +0000 *** This bug has been marked as a duplicate of bug 251023 ***
