           Summary: kst causes X to consume mucho resources when an invalid
                    vector is being displayed
           Product: kst
           Version: unspecified
          Platform: SuSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kst at kde.org
        ReportedBy: matt at truch.net


Version:           0.92 (using KDE KDE 3.1)
Installed from:    SuSE RPMs
OS:          Linux

When kst trys to display a curve which contains a vector with an invalid field, the refresh of kst races, and X consumes alot of CPU (and/or bogs down the graphics card).  

To reproduce:  Open a new kst, click on quickly create a new curve.  Choose a valid filename and valid X vector (ie "INDEX"), but a nonexistant Y vector (eg "IJGLKSDNLKFSAJD").  Click OK.  A dialog will pop up saying you have choosen an invalid vector, but kst will refresh repeatadly anyways.  Clicking pause temporarily fixes the problem (until you run again), and removing the vector (through the data manager) fixes the problem until another bunk vector is added.  

Expected behavior:  kst should not race when an invalid vector is loaded.
