More info on this bug and a patch can be found on: http://bugs.python.org/issue2693
The issue also breaks the calltips, resulting in an Exception in tkinter. Root cause is the incompatibility of python2.5 with tcl8.5, which is the version of tcl used by python-tk in squeeze. Support for tcl8.5 won't be backported to python2.5. A patch fixing at least idle is available on the link above, but it is unclear if it will break other programs: The patch needs to be applied against the idlelib, which is part of the python package.
