           Summary: dock icons are lost in some cases when applications fork
           Product: kdelibs
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: kdecore
        AssignedTo: kdelibs-bugs kde org
        ReportedBy: ranger befunk com


Version:            (using Devel)
Installed from:    Compiled sources
Compiler:          gcc 4.0.1 i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5465) 
OS:                OS X

When an application is started from the command-line (or exec) instead of through the finder, and it is an application which forks (KUniqueApplication, or in some cases, kdeinit4 apps), it does not get a dock icon.

I suspect it is because we need to fork-and-reexec when forking, unlike on linux/etc. where there is no issue continuing CoreFoundation code after a fork.

It might be as simple as re-registering as a GUI app or re-setting the dock icon, or it may be something deeper; we need to investigate more.
