           Summary: kde4d crash in nanosleep
           Product: kde
           Version: unspecified
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: PTrenholme at 4DV.net


Version:           kde4d (using KDE 4.3.0)
Compiler:          gcc 4, i86_x64 
OS:                Linux
Installed from:    Fedora RPMs

Daemon crashed during a (long - 240Mb) update on Fedora 11 x86_64. The
backtrace seems to finger nanosleep(), which I didn't see listed in the other
kded4 crash reports. Note that the daemon restarted and hasn't crashed again.

Backtrace:

Application: KDE Daemon (kded4), signal SIGABRT
