  This is a crash in the memory allocator.

  Can you file a bug report against Kst at http://bugs.kde.org/ with a full 
step-by-step of how to reproduce it including any files we might need?  Also 
a stack trace would help.  You can get one by running Kst in gdb if drkonqi 
is not showing up.  I have netcdf setup here so I can test and see if it's a 
Kst bug, a netcdf bug, or a datasource bug.

   They should be interpolated as needed, so it should work.  I don't know of 
any cases of vectors (off-hand) that can't be mixed.
