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.
