Either the UPower dbus interface doesn't exist or the EnumerateDevices call fails (times out?) I don't think it's the dbus interface because the upower backend shouldn't get loaded if the upower interface doesn't exist. Can you tell me the result of "dbus-send --print-reply --system --dest=org.freedesktop.UPower /org/freedesktop/UPower org.freedesktop.UPower.EnumerateDevices" and roughly how long it takes to return?
It indeed looks like a timeout: (tested on openSUSE Factory) # time dbus-send --print-reply --system --dest=org.freedesktop.UPower /org/freedesktop/UPower org.freedesktop.UPower.EnumerateDevices Error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. real 0m25.063s user 0m0.001s sys 0m0.001s
{ time dbus-send --print-reply --system --dest=org.freedesktop.UPower /org/freedesktop/UPower org.freedesktop.UPower.EnumerateDevices; } method return sender=:1.2 -> dest=:1.69 reply_serial=2 array [ ] real 0m0.027s user 0m0.001s sys 0m0.004s
Created attachment 77772 [details] Patch to avoid crash Can you try this patch? This should avoid the crash but won't prevent the slow login. So could you also file a bug with opensuse or upstream upower about the timeout from the EnumerateDevices call and link to it here? That way we can get to the bottom of what's up with upower.
I created test packages with the patch added: https://build.opensuse.org/package/show?package=kdebase4-workspace&project=home%3Acboltz%3Abranches%3AKDE%3ADistro%3AFactory and will report back if they fix the crash. I also opened a bugreport for upower: https://bugzilla.novell.com/show_bug.cgi?id=807616
According to https://bugzilla.novell.com/show_bug.cgi?id=807616#c2 upowerd isn't starting. So powerdevil should be bailing out earlier and not trying to use the upower backend.
I didn't see a crash dialog since I installed the patched package, which means your patch probably works. Some minutes ago I updated to latest openSUSE Factory which fixed the problem with policykit and upowerd, which means I'm no longer available as tester ;-)
Best to try and fix this so that powerdevil will check that the upower dbus service get started properly.
