[vtkusers] Conditional jump or move depends on uninitialized values(s)

[John Haiducek]

When I run the following program under valgrind I get lots of warnings
saying "Conditional jump or move depends on uninitialized values."
Does this indicate that I'm doing something wrong, or are these false
positives?
