           Summary: filtering an equation crashes kst.
           Product: kst
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kst kde org
        ReportedBy: netterfield astro utoronto ca


Version:           0.99-devel (using KDE 3.2 BRANCH >= 20040204, Mandrake Linux Cooker i586 - Cooker)
Compiler:          gcc version 3.3.2 (Mandrake Linux 10.0 3.3.2-6mdk)
OS:                Linux (i686) release 2.6.3-7mdk

filtering an equation crashes kst.  Fitting appears to be fine (other than jagged lines in real time mode).

How to reproduce:
plot an equation in kst, eg
kst --xe 0:100:100 -ye 'sin(x/5)'

apply a filter (plot->rmb->filter->...)
eg, Butterworth-lowpass, order 4, Cutoff 0.1)
kst crashes.

Note that a fit works fine.
