With the latest NB6.0 nightly bits...

Without compilers/gdb included in the PATH, 
  launch the IDE and create a sample Quote project.

A popup with the "gdb: not found" msg appears as expected; click OK.

Per gordonp, this is a known problem that needs to be documented.
Comment 1 _ gordonp 2007-07-04 00:10:10 UTC 
Fixed. Check for null object and skip dereferencing it if null. Also use Build Tools
to ensure a gdb command is available.
