           Summary: curve fitting freezes kst
           Product: kst
           Version: unspecified
          Platform: unspecified
        OS/Version: Solaris
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kst kde org
        ReportedBy: nicolas.brisset eurocopter com


Version:           1.2.0_devel (using KDE 3.4.0, compiled sources)
Compiler:          gcc version 3.4.3
OS:                SunOS (sun4u) release 5.8

To reproduce:
- in a kst session, call the datamanager
- generate a vector V0 (e.g. from -10 to 10, 1000 points)
- generate a new equation like: 1.27*[V0]^3 + 2.43*[V0]^2 -3.21*[V0] + 7.47
- in the plot dialog, context menu, call "Fit", choose polynomial (it seems to exhibit the same behavior with other fit plugins, but I haven't tried too many), order 3
- click OK: kst is frozen and eats up all your CPU :-(

kst 1.1.0 does not have this problem. As said previously, it seems to AFFECT ALL FIT AND FILTER PLUGINS, invoked from either the contextual menu or the datamanager and the only solution is KILLING KST ! This is pretty bad and needs to be fixed before 1.2.0 comes out !
