           Summary: kst uses up all cpu when a file in the format file isn't
                    present
           Product: kst
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kst at kde.org
        ReportedBy: matt at truch.net


Version:           0.94 (using KDE KDE 3.1)
Installed from:    Unspecified Linux

If you choose a valid (according to the format file) vector, but that vector doesn't exist on disk (ie you didn't copy the whole data set from another location), kst uses up 'mucho' CPU.  

How to reproduce:  Within a dirfile, delete one of the elements.
open kst, and create a curve which uses the deleted element (either directly, or a derived vector that deponds on it)

Expected Behavior: kst won't use up much CPU, and just ignores the file (or pops up a dialog box to complain, etc).
