I opened my project in Netbeans 4.1, then switched
back to Netbeans 4.0, Qbuild 11/02/2004.

Now, I constantly get exceptions and scanning. 
For example, when I do a "Replace", I can't
finishing typing a word, and the following scan
and exceptions show up.  I know that moving back
from 4.1 to 4.0 is an odd thing to do.  Howerver,
I report the bug here incase the exception and
stack trace may provide some valuable clues on
future error.  (note that now I cannot use 4.0
anymore because of this).
