           Summary: attempting to plot a non-existent equation crashes.
           Product: kst
           Version: 1.0.0
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kst kde org
        ReportedBy: dwiebe physics utoronto ca


Version:           1.0.0 (using KDE 3.3.1, compiled sources)
Compiler:          gcc version 3.3.4
OS:                Linux (i686) release 2.6.9

Trying to create a plot from an equation that hasn't been specified crashes kst.

Steps to reproduce:

1.  start kst with no command line options.
2.  Data Manager
3.  New Equation...
4.  Click OK (here, by default, there's nothing in the "Equation:" box and the independant variable vector is 1000 samples generated from -10.0 to 10.0)

Reproduceable every time.
