Bug 204457

Application that crashed: kpilotDaemon
Version of the application: 5.3.0 (KDE 4.3.0)
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.23 i686

What I was doing when the application crashed:
Starting kpilot from command line brings kpilot widget up, kpilotDaemon starts, then message '.kde.kpilot.daemon was not provided by any .service files', then HotSync is disabled because screen saver feature is not set (it is set, but that's another matter). HotSync cycle runs OK, though obviously with no actual sync taking place.  Then when kpilot tries to open the device (usb:), kpilotDaemon crashes.
Running kpilotDaemon independently produces the following on the console:
!
!    Unable to do dlp_ReadSysInfo
KCrash: Application 'kpilotDaemon' crashing...
sock_file=/home/cam/.kde/socket-treehouse/kdeinit4__0

hence the subject line.

At the moment, the system is more-or-less running kde4, but with some kde3 apps.
