           Summary: [crash] almost randomly using konqueror
           Product: kdelibs
           Version: 4.1
          Platform: FreeBSD Ports
        OS/Version: FreeBSD
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: klauncher
        AssignedTo: kdelibs-bugs at kde.org
        ReportedBy: bugzilla at soulrebel.in-berlin.de


Version:            (using KDE 4.1.1)
OS:                FreeBSD
Installed from:    FreeBSD Ports

Once in a while Konqueror on Filebrowser mode tells me that it lost connection
to klauncher or in Webbrowser mode it tells me that it cannot initiate its
foo-kio-slave, because it cannot contact klauncher.

This Konqueror-session is than completely useless and has to be closed, however
other Konqueror sessions are not effected.

Also I have realized that often (not always) this behaviour seems to follow
immediately after starting a new Konqueror session, i.e. SessionA is open, I go
to to a different virtual Desktop and open SessionB => SessionA loses its
klauncher. Apperently klauncher crashes in the background (see below).

The issue happens rather often (once in an hour at least), I have had it since
4.1.0, but it seems to be happening more often of late (although that might
just be perception).

Since Konqueror is rather slow on FreeBSD vs Linux, problems communicating with
klauncher could be related.

Thank you very much! 

Heres the backtrace on ~/klauncher.core (dont know if its useful):
