Does this in fact work on your system? On mine (2.4.1 (#65, Mar 30
2005, 09:13:57) [MSC v.1310 32 bit (Intel)]), it doesn't seem to. I
if msg.find("iteration over non-sequence") >= 0:
... but I got a traceback, and
AttributeError: TypeError instance has no attribute 'find'
... which leads me to belive that 'msg' is not type(str). It can be
coerced (str(msg).find works as expected). But what exactly is msg?
It appears to be of <type 'instance'>, and does not test equal to a
string. This is not the least surprise to me.
