Version: (using KDE 4.0.98) Installed from: Debian testing/unstable Packages After having logged in and used KDE4 for a little while, maybe an hour or two in this case, some menu items have stopped working. I think it is all the menu items corresponding to KDE4 applications, but also some others. The menu item for e.g. LyX still works fine, but the GQView menu item does not work. GIMP also does not work, but Openoffice works. None of the KDE4 programs I have tried works now, i.e. kmix, kjots, konqueror, konsole, okular. Everything works immediately after login. Best regards, Torquil Sørensen
I can point out that krunner stills works, so I always use that after the menu stops working. Btw, I use the Classic style menu, not KickOff. Best regards, Torquil Sørensen
Does anybody know how I would go about debugging this? Nothing seems to appear in .xsession-errors after I try a menu item.
I can confirm this bug on KDE 4.1. I use the classic KMenu.
Torquil: you won't get any debugging info on the console unless you actually build a debug version. There are instructions on Techbase to do this at http://techbase.kde.org/Getting_Started/Build/KDE4.1. If you are willing to build a debug version from the 4.1 branch, that would be really helpful in debugging - I can't reproduce the problem in trunk.
I could build a debug version to help you track down that bug. Do I need to build debug versions of all KDE components or is it enough to build a debug version of plasma?
plasma (well, kdebase-workspace) and kdelibs should be all we'd need. Then if you could run kdebugdialog and make sure "kio (KRun)" and "kdecore (KService)" are selected, before running plasma, that would be great.
I kept plasma running for 2 days in debug mode. Today, after resuming work on my computer, I noticed that most (all?) menu items do not work, i.e. the chosen application is not started. There is, however, NO debug output in this case. Other features of the taskbar still work, for example opening one of the plugged in devices, and result in the following output: plasma(29558) DeviceNotifier::slotOnItemClicked: QModelIndex(3,0,0x763630,QStandardItemModel(0x8c4d80) ) plasma(29558) DeviceNotifier::slotOnItemClicked: DeviceNotifier:: call Solid Ui Server with params : "/org/freedesktop/Hal/devices/volume_uuid_8a803796_edeb_41f0_a0b4_e89a8cb37d76" , ("test-predicate-openinwindow.desktop") I will keep the problematic plasma process running and can provide you with an strace of this process. A quick look at it did not give me any hints about what could be wrong, though.

Update: about 1 hour after I noticed that the menu items stopped working, the plasma process crashed. I am not sure if these two problems are related. Plasma crashed for the first time on my machine, whereas the menu item problem was there already a couple of times. Please see the previous two attachments.
I had been suffering from this, (No crashes) but after KDE 4.1.1 I haven't seen this problem anymore.
Confirmed. KDE 4.1.1 and 4.1.67 apparently fixed that bug.
