Ned Deily added the comment:
Unfortunately, we didn't test this change with Tk 8.4: TkFixedFont does not
exist in 8.4. This means that, unless the user has already modified the IDLE
configuration to use an explicit font, IDLE linked with Tk 8.4 crashes in
initialization.
$ mv .idlerc/ .idlerc-OLD
$ idle3.5

A workaround is to manually create or edit the IDLE configuration file and
define an explicit font, for example on OS X:
$ cat >.idlerc/config-main.cfg <<EOF
[EditorWindow]
font-size = 11
font = monaco
EOF
This is a release blocker for 3.5.0, first seen in 3.5.0rc1.
