Created attachment 77408 [details] New crash information added by DrKonqi systemsettings (1.0) on KDE Platform 4.8.5 (4.8.5) using Qt 4.8.1 - What I was doing when the application crashed: Steps to repeat error: 1.) Open [System Settings] from the "kickoff application launcher". 2.) In the 5th section down tittled "System Administration" Open [Date & Time] 3.) Just below the "Date and Time" tab is a check box titled "Set date and time automatically", make sure this box has a check mark in it. If this box already has a checkmark then click on it twice to remove and reapply the check mark so the "apply" button in the lower right hand side of the window is enabled. 4.) Click the "Apply" button in the lower right hand side of the window. Results from Step 4: All items in the window become greyed out for a moment and unclickable, then all items return to there normal color and are now enabled or clickable again. 5.) From here there are two options one that leads to a crash and one that does not. option-01_(non-crash).1) Click on "Overview" in the upper left hand corner. option-01_(non-crash).2) An "Apply Settings - System Settings" dialog appears with the button options of "Apply" "Discard" and "Cancel". Click on "Apply". The system is updated as it should and everything seems fine. option-02_(crash).1) If you are not currently at step 5, then repeat steps 1 through 5 and instead of doing option-02_(crash).2), now do this: Click "Apply" in the lower right hand corner. Results from option-02_(crash).2: Everything except the "Apply" button is greyed out for a moment then comes back as normal. option-02_(crash).3) Notice that if you click the "Apply" button the "Apply" buttin itself is not greyed out and the user can still click on it while everything else is still updating. This is the step where reproducing the bug becomes possible. To reproduce the bug at this step simply click the "Apply" button, and while everything else is still greyed out click the "Apply" button again, then follow the rest of the steps in quick succession which is what I think other people have been doing. Results from option-02_(crash).3: An error message appears tittled "Error - System Settings" with the message "Unable to authenticate/execute the action: 6," with an "OK" button. Quickly select the "OK" button then either try to reapply the "Apply" button in the lower right hand corner, or go back to the overview page by quickly selecting "Overview" in the upper left hand corner followed by "Apply" in the window that appears and the Settings Manager will crash. In other words, users are impatient and if something is available to click on the user interprets this as a notice that what they did didn't work, so they click on it again. To avoid this, I suggest not only greying out the "Apply" and "Overview" buttons, but also display a short message saying something like "please be patient, the settings are being updated" in order to avoid future bug report floods. -- Backtrace (Reduced): #7 0x00007f808fa2ebf2 in QObject::connect (sender=0x16d9770, signal=<optimized out>, receiver=0x1140180, method=0x7f807afe53f1 "load()", type=Qt::AutoConnection) at kernel/qobject.cpp:2588 #8 0x00007f808fa3695a in QSingleShotTimer::QSingleShotTimer (this=0x16d9770, msec=5000, receiver=0x1140180, member=0x7f807afe53f0 "1load()") at kernel/qtimer.cpp:300 #9 0x00007f808fa36b0e in QTimer::singleShot (msec=5000, receiver=0x1140180, member=0x7f807afe53f0 "1load()") at kernel/qtimer.cpp:363 #10 0x00007f807afe3840 in KclockModule::save (this=0x1140180) at ../../../kcontrol/dateandtime/main.cpp:109 #11 0x00007f8091a33997 in KCModuleProxy::save (this=<optimized out>) at ../../kutils/kcmoduleproxy.cpp:279

After I had entered root password, I clicked on the Overview button then I was asked to enter root password again. After I had entered it, I saw this message: "Unable to authenticate/excute the action: 6,".
