Description of problem: I upgraded my Fedora 13 systems to KDE 4.5.2 this morning and now when I login I just get a blank screen with two xterms (started by my ~/.kde/Autostart/terminals.sh script). According to 'ps', kwin and plasma and the other daemons are all running, but there's nothing on the screen. The mouse buttons are not bound to anything on the desktop. I moved my ~/.kde directory out of the way and started with a fresh profile and it launched correctly, but when I restored my ~/.kde directory it broke again. I could start from scratch, I suppose, but it would take me quite some time to customize everything the way I had it. I looked at ~/.xsession-errors and noticed this: <unknown program name>(1926)/: Communication problem with "plasma-desktop" , it probably crashed. Error message was: "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." " I'll try and figure out which of my ~/.kde files is causing this. Version-Release number of selected component (if applicable): kdebase-4.5.2-2.fc13.i686 How reproducible: unsure Steps to Reproduce: 1. upgrade to kdebase-4.5.2-2.fc13.i686 2. login to KDE Actual results: KDE doesn't start Expected results: KDE starts normally Additional info:
I started with the obvious and removed these three files: ~/.kde/share/config/plasma-desktoprc ~/.kde/share/config/plasmarc ~/.kde/share/config/plasma-desktop-appletsrc and now KDE starts! I wonder what it didn't like about my old files. I have to setup my widgets again, but at least the rest of my customizations are preserved.
Which applets/plasmoids were you using? Mind attaching the contents of those files?
Created attachment 459815 [details] plasma config files I had removed the Desktop folder viewer widget and I added the the World Clock widget. The files are attached.
It appears that the World Clock widget is the culprit. I just tried adding it back to my desktop and plasma locked up on me. I restarted plasma and tried again and it locked up a second time. Does it start for you? This widget comes from kdeedu-marble: $ rpm -qf /usr/lib/kde4/plasma_applet_worldclock.so kdeedu-marble-4.5.2-2.fc13.i686
Looks like it's been reported upstream too: https://bugs.kde.org/show_bug.cgi?id=256193
Thanks! excellent detective-work, I've used it in the past, but not recently... I'll try world clock again to test.
This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '13'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 13's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 13 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
It still crashes with Fedora 15
crashes or hangs? The referenced upstream bug was presumably fixed in kdeedu-4.5.5 series, fwiw, so perhaps you're seeing something different?
Oh, you're right, this might be different. This morning I tried adding the World Clock to my desktop and it crashed (the KDE bug catcher popped up). I just tried again, however, and it successfully launched. I removed it and added it again a few times and it's launched every time. I'll keep my eye on it and open a new BZ if it crashes again. In the meantime, I guess this one can be closed now.
OK, there's in interesting bug we found testing the kde-4.6.x f14 updates. After upgrading from < kde-4.6.x, anything marble-related would crash *once*, afterwhich, all is fine. I'd bet you just hit the one-time anti-fun. :(
