Fixed KW Warnings based on using uninitialized values

Fixed KW Warnings based on using uninitialized values

The values adjusted here were improperly initialized, so these
fixes ensure that they are only used when properly initialized.

Note that in the second case, we were checking for NULL, but
dereferencing anyway.  This adds an else case to avoid that.
