error converting list to tuple

[Stefan Seefeld]

hi there,

I'm trying to convert a tuple to a list,
and get a 'TypeError: list objects are unhashable'.

Can anybody enlighten me as to the possible causes
for this ? Where does hashing come into play during
this conversion ?

Could it be that my runtime is corrupted ?
The code is executed from within a C++ extension
module I'm developing...

Thanks for any help,
		Stefan

PS: I'm using python 2.3.3 in case that matters
