           Summary: example netcdf file complains "You cannot load this
                    much data"
           Product: kst
           Version: 1.7.0
          Platform: Debian unstable
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: datasources
        AssignedTo: kst at kde.org
        ReportedBy: timo.lindfors at iki.fi


Version:           1.7.0 (using KDE 4.4.3) 
OS:                Linux

Steps to reproduce:
1) cat > testcase1.cdl <<EOF
netcdf foo {  // an example netCDF specification in CDL

dimensions:
     lat = 10, lon = 5, time = unlimited ;

variables:
     long    lat(lat), lon(lon), time(time);
     float   Z(time,lat,lon), t(time,lat,lon);
     double  p(time,lat,lon);
     long    rh(time,lat,lon);

     // variable attributes
     lat:long_name = "latitude";
     lat:units = "degrees_north";
     lon:long_name = "longitude";
     lon:units = "degrees_east";
     time:units = "seconds since 1992-1-1 00:00:00";
     Z:units = "geopotential meters";
     Z:valid_range = 0., 5000.;
     p:_FillValue = -9999.;
     rh:_FillValue = -1;

data:
     lat   = 0, 10, 20, 30, 40, 50, 60, 70, 80, 90;
     lon   = -140, -118, -96, -84, -52;
}
EOF
2) ncgen -b -o testcase1.netcdf testcase1.cdl
3) kst
4) Data Wizard
5) select testcase1.netcdf
6) select all data columns
7) Next, Next, Finish

Expected results:
7) kst opens testcase1.netcdf

Actual results:
7) kst prints

"You requested to read in over 16777215 TB of data but it seems that you have
approximately only 0 TB of usable memory available. You cannot load this much
data."

More info:
1) The example is from the manual page of the ncgen command that I use to
generate netcdf files.
2) If I select only lat and lon columns then kst does not crash and opens the
data successfully. Maybe the crash is related to the fact that other columns do
not have data points in this file?
3) I am not quite sure which version of KDE is in debian unstable:

$ COLUMNS=100 dpkg -l | grep kde

suggests 4.4.4 but that option is not available in bugs.kde.org.
