so it crashed when an item being started finished starting (the loop involving QMutableHashIterator<StartupPtr, TaskItem*> it(d->startupList); in GroupManager::add(TaskPtr task) ... really hard to trace what the exact problem would be from that backtrace; the code _looks_ correct there. does it continue to crash on startup, or was it just that once? if you log in as the user, delete the config files, and start plasma manually does it crash? do you get a crash when it starts at same time something else is starting? It crashed only once with an empty home and dot directories, but once the config files and dot directories are populated with the config after first login, it does not crash any more on startup. This is what I did now: Clean home and dot directories logged in and the whole desktop hung. I did not see any cpu chewing process. So had to kill X with CTRL+alt+bkspace On next login I deleted plasma-appletsrc and plasmarc the files in .kde4/share/config and tried to run ./kquitapp plasma which gave me an error: "Application plasma could not be found using service org.kde.plasma and path /MainApplication." So I tried killall plasma and ran ./plasma and the whole desktop hung after plasma loaded. No cpu chewing process that i can see in top and I had to kill the Xserver again. Now I tried all the above *again* but instead of running ./plasma i ran gdb ./plasma and it still hung the whole desktop no response from gdb either on the xterminal. The only output i can see at the end is: kbuildsycoca4(8890) KMimeFileParser::parseGlobFiles: Now Parsing "/home/kde-devel/share/mime/globs2" and thats the last output i can see on my xterminal with no disk activity or cpu activity, so I had to restart X again. Please let me know what else I can try to find out the source of problem. Regarding my Comment #2, I should say that now it crashes on random not just on login. as for my comment #3, do you want me to file a separate bug report? I am not sure what other info I can provide other than what i have provided in comment #3. i'm going to guess that the issue is that there is a jumble of incompatible libraries and plugins on your system that have built up as we've worked on 4.2. if you haven't already, can you try removing the installation directory and re-installing your kde4 build? I will give that a go. I am going to cleanup my svn and installed dir and do everything when i get back home tonight. Await the results in another 10-12hrs :) This is what I tried: complete reconfigure and recompile of qt-copy and kde base/libs and friends. clean home and dot dirs before login. on login bam, desktop loaded then the whole desktop is stuck, no response to keyboard (alt+f2), mouse moves but cannot click on any desktop component, no cpu or harddisk activity after loading. killed X ctrl+alt+bkspace and on next login everything is running fine. How to proceed to get more info on this bug > then the whole desktop is stuck, no response to keyboard (alt+f2)
that's not plasma. that's kded4. this implies that something is, at least on first start, freezing up kded4 either permanently or for an extended period of time.
plasma is probably affected because it gets stuck doing a d-bus call that ends up in kded4 somewhere, probably registering a global shortcut.
looking at the global shortcuts dbus interface (kdelibs/kdeui/shortcuts/kdedglobalaccel_interface.h), all the calls there are blocking, even though the API that uses them doesn't always need the returns.
these calls really ought to be made non-blocking (async) so as to avoid being hung by d-bus.
Andreas: thoughts?
if it is dbus/hal I should also mention that i am running ubuntu 7.10 (gutsy) with libhal 0.5.9.1 and libdbus-1-3 v.1.1.1.3, any problems with those versions? I also have seen sometimes kded4? unable to connect or disconnected to hal/dbus. once it happened and when trying to navigate a directory in dolphin it gave some error, althought it happened only one of two times. Seems like there is an output bug somewhere? first of all this is how i run kde, i also clean the .dirs for kde-devel as user login from gdm to failsafe Xmode which presents me with an xterminal only. 1. i ssh -X kde-devel@lappy 2. source .bashrc #this contains all the kdesettings borowed from the techbase .bashrc settings for kde4 - modified appropriately to set correct directories for kdehome, kdedir, qtdir etc 3. cd kde/bin 4. ./startkde # from the xterminal, after mostly loading it just hangs, but i have just tried ./startkde &> out.txt instead of ./startkde above and the whole desktop loads without problems... hurray so far from testing: ./startkde &> out.txt # WORKS, no idea why this actually works The ones below don't work ./startkde 2>&1 >> out.txt ./startkde & ./startkde *** Bug 175342 has been marked as a duplicate of this bug. *** both reporters are using svn sources. can you both note what revision was giving you the crash? thanks.. hmm I forgot to take a note of the svn revision for the crash, but if you can find the closest match for a svn revision for the date(the same day as i posted the bug report) should be enough? The bug was reported on 2008-11-10 15:24. Aaron, if you mean me by the second reporter: I use KDE-4.1.73 (self compiled via a gentoo overlay containing weekly snapshots). So the exact revision would be the one that was tagged as 4.1.73. Further information that might be interesting after I read this bugreport: - I already had previous KDE-4.1.xx snapshots installed, so I was using an old configuration (from like KDE-4.1.71) that however was pretty standard - The time I logged out before the crash I had to kill the X Server via CTRL+Alt+Backspace because KDE did not shut down properly. (Krunner crashed, I wanted to save the backtrace, but after I closed the crash report the logout procedure did not continue, so I restarted the X Server in the aformentioned way) i can confirm again in svn (kdebase/kdelibs): 886841. attached latest bt

I'm using KDE4.2.
When KDE started, I fired up firefox, kontact, pidgin and xchat, all at the same time, then, when I clicked the pidgin window in the taskbar, plasma crashed.
Reopen if you feel this is not fixed.

I added the backports repository to upgrade my KDE to 4.3.2. After the downloading and committing, I restarted my PC and now I am also stuck with this Plasma Workspace crash problem after logging in when starting up. @Marius Groenewald: install the "kdebase-workspace-dbg" package and report a new bug (using the Crash Handler "Report" feature).. This crash was fixed some time ago, and you are probably getting a different one. Thanks Thanks for the lightning fast response. Wow! Dario, before I opened my mailbox to read your solution, I tried a different approach that also worked. I also have the Gnome GUI installed on my laptop, so I rebooted into Gnome and ran Gnome´s Update Manager. It immediately recognised that I was busy with a Partial Upgrade (KDE 4.2.2 to KDE 4.3.2). It downloaded the necessary kdm files and installed. After I rebooted my laptop, everything was working fine. That´s why I love Linux - the support is out of the Windows. |
