I have got the least version of qt-copy/kdepim/kdelibs/kdepimlibs, but still met this problem. Debug info followed, nothing curious: kresources: Factory::self() kio (KSycoca): Trying to open ksycoca from /var/tmp/kdecache-kde4/ksycoca4 kio (KTrader): query for serviceType KResources/Plugin : returning 2 offers kresources: ManagerImpl::ManagerImpl() kresources: ManagerImpl::readConfig() kresources: Factory::self() kresources: ManagerImpl::readResourceConfig() KBxuTKJZmc kresources: Factory::resource( file, config ) knotes: ResourceLocal::ResourceLocal() knotes: Opening resource Notes kresources: Opening resource Notes libkcal: ICalFormat::load() /home/kde4/.kde/share/apps/knotes/notes.ics libkcal: Set custom property [X-KDE-KNotes-BgColor=#ffff00] libkcal: Set custom property [X-KDE-KNotes-FgColor=#000000] libkcal: Set custom property [X-KDE-KNotes-RichText=false] libkcal: Set custom property [X-KDE-KNotes-BgColor=#ffff00] libkcal: Set custom property [X-KDE-KNotes-FgColor=#000000] libkcal: Set custom property [X-KDE-KNotes-RichText=false] knotes: [void KNoteEdit::slotCurrentCharFormatChanged(const QTextCharFormat&)] knotes: WARNING: KFontSizeAction: Size 0 is out of range kdecore (KConfigSkeleton): Creating KConfigSkeleton (0x8210178) kdecore (KConfigSkeleton): KConfigSkeleton::readConfig() knotes: [void KNoteEdit::slotCurrentCharFormatChanged(const QTextCharFormat&)] knotes: WARNING: KFontSizeAction: Size 0 is out of range kdecore (KConfigSkeleton): Creating KConfigSkeleton (0x8223a40) kdecore (KConfigSkeleton): KConfigSkeleton::readConfig() kdecore (KConfigSkeleton): Creating KConfigSkeleton (0x81cf628) kdecore (KConfigSkeleton): KConfigSkeleton::readConfig() knotes: ERROR: Communication problem with knotes, it probably crashed. knotes: Error message was: org.freedesktop.DBus.Error.NoReply: "Message did not receive a reply (timeout by message bus)" yukikaze:~/build_knotes$ KCrash: crashing... crashRecursionCounter = 2 KCrash: Application Name = knotes path = pid = 24361 Warning: connect() failed: : Connection refused KCrash cannot reach kdeinit, launching directly. kdeinit: Pipe closed unexpectedly: No such file or directory kdeinit: Pipe closed unexpectedly: No such file or directory kdeinit: Communication error with launcher.
