Python plugin fails to install in Intellij IDEA 12.1.4

When I try to install the Python plugin in a fresh install of idea (downloaded this morning) I get the following failures:

(from browse repositorites):
     Failed to Download
     Plugin Python was not installed: Invalid filename returned by a server

(from install plugin from disk, using the currently available python-1078.zip, again downloaded this morning):
     Plugin Python incompatible with current installation

I have confirmed this behavior on Windows 7 (64 bit) and Ubuntu 13.04 (32 bit) using the latest JDK (1.7.0_25-b15 on ubuntu, 1.7.0_25-b17 on Windows 7)
