I don't specifically know about Eclipse.

In WingIDE, there are some spurious exceptions reported; the WingIDE 
docs explain that they are sometimes unable to determine if an exception 
is being caught or not, and say that exceptions which are not reported 
when the app is run outside the debugger are likely to be instances of 
this problem - and the advised action is to mark them as "Ignore this 
exception" (or some similar thing). I've always done that and had no 
problems.

(Except that now I can't debug in WingIDE at all - but that's got to be 
just a side-effect of me messing around with versions of Python 
incorrectly. I hope.)
