I think Chacko is right, that the "expected" behavior of a "Save As..." 
operation is to overwrite what's already there, even though we haven't 
ever worried about this before.  However, considering that this is a 
potentially time-consuming operation (to rm -rf a directory), 
potentially very destructive, and also rare, I think that perhaps an 
extra warning message is warranted: "Are you sure you want to delete 
the [X] MB of audio data belonging to the previous project titled 
[foo].aup?".  The widgets/Warning.cpp code should be used and/or 
extended - it's intended to be a central implementation of warning or 
redundant-question type dialogs that have a "Don't ask me again!" 
checkbox or something like that.
