Version: (using Devel) Compiler: gcc-4.2.3 OS: Linux Since quite recently (maybe one or two weeks ago), kded4 dies/terminates quite regularly on all of my KDE4 machines. I usually notice when Alt+F2 does not work anymore, or cookies are ignored. Restarting kded4 makes everything work again. As it stands now, it dies several times a day. I couldn't figure out yet how to get a backtrace or other useful output from kded4 that might help in finding the issue; if you have hints or need more information, please tell me.
Argh, missed a possible/probable duplicate again. Bug 156087 seems to be the same issue. Sorry for that, we used quite different keywords I guess :)
Lately (i.e. since my last update yesterday, I guess, though I can't pinpoint), the silent termination seems to have been mostly replaced by frequent hanging (see also Bug 161733). Happens every few minutes now. In these cases, I need to kill -9 kded4 to make KDE4 work again. Haven't had kded4 die since, but that might well be because I keep killing it myself...
Terminates again on my laptop all the time. Finally managed to get a backtrace: (gdb) run --nofork Starting program: /usr/kde/svn/bin/kded4 --nofork Program received signal SIGSEGV, Segmentation fault. 0x08176f47 in ??

I have the same problem. It comes with this error message: kded(9000): Communication problem with "kded" , it probably crashed. Error message was: "org.freedesktop.DBus.Error.NoReply" : " "Message did not receive a reply (timeout by message bus)" "
Same problem. kded(4947): Communication problem with "kded" , it probably crashed. Error message was: "org.freedesktop.DBus.Error.NoReply" : " "Message did not receive a reply (timeout by message bus)" "

For the favicon crash, please test http://web.davidfaure.fr/kde/favicons.cpp.diff ( from the code: this can only happen when you go to a site which has a HUGE favicon file....) For other kded crashes, please see Bug 162140.
Wow http://planet-soc.com/favicon.ico is big indeed. 133K. file(1) says MPG sequence, but xli says: favicon.ico is a 576x720 MacPaint image. Not that it can display it though. OK the crash depends on a race condition between "end of download" and "kill thisdownload", I think, and my patch addresses that, but I can't trigger the crash here yet; I'll leave it running to see if it happens. I'll fix the code (also for the warning from ~SimpleJob).
SVN commit 825063 by dfaure: Fix crash when aborting download of a too big favicon. http://planet-soc.com/favicon.ico is a strange file indeed, can't figure out its format :) BUG: 161734 M +10 -4 favicons.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=825063
