Well, if you are calling this “cdbc” alias in your .profile that  
explains it.  The python bundle expects to be in the same directory as  
the script you are attempting to run.  When you change dirs, you are  
no longer in that directory and so you get undefined behavior.  Still,  
it doesn't seem like it should be nulling your file.  The  
save_current_document code reads STDIN (which TextMate is supposed to  
have written the document contents on) and then just writes that to  
TM_FILEPATH (the file you are currently editing).  Is (was?)  
your .profile reading stdin by any chance?  That would explain why  
save_current_document was erasing your file.
