The latest bugfix release for the KDevelop 1.4 branch is currently 1.4.2 and is considered stable by upstream — this should be a simple version bump; and for the KDevelop 1.5 branch, the latest is 1.5.1, which I would suggest to keep as testing since KDevelop 1.5/4.5 is still considered as such in Gentoo.
1.5.1 in overlay, no reason to add 1.4.2 as 1.5.1 will follow to tree shortly.

This makes sense if also 4.5.x of KDevelop will become stable at the same time. Otherwise the 1.4.x branch has to be bumped in order to work with the stable 4.4.x KDevelop branch.
kdevelop-python-1.5.1 is now in CVS, and we are stabilising kdevelop-4.5.1 in bug #476510.
