           Summary: "Change data sample ranges" dialog freezes kst with some
                    datasources
           Product: kst
           Version: unspecified
          Platform: unspecified
        OS/Version: Solaris
            Status: NEW
          Severity: normal
          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

[This is quite bad as your kst session needs to be killed !!!]

The "Change data sample ranges" wizard freezes kst with some datasources, like CDF and netCDF. 

To reproduce (you need to have the netCDF datasource working):
- download an example netCDF file with 1D variables, e.g. http://www.unidata.ucar.edu/software/netcdf/examples/GOTEX.C130_N130AR.LRT.RF06.PNI.nc
- load some variables (e.g. "kst -x time_offset -y ADIFR")
- go to Tools->Change data sample ranges
- check "Count from end"
- type "200" in the "limit" field (or whatever it's called in English :-))
- hit "Apply": kst is FROZEN and can only be KILLED :-( !

This used to work, and still works with ASCII. I suppose there has been a minor change somewhere in kst that has not been propagated to all datasources, as CDF also exhibits the same problem. Hopefully this can be fixed easily...
