Storm 0.15 from PPA post-install script crashes on Ubuntu Jaunty

[GabrielGrant]

When installing or upgrading storm 0.15 from the Jaunty PPA, the post install script fails.

Synaptic gives the error:

E: python-storm: subprocess post-installation script returned error exit status 1

The full traceback points to a problem with pycentral:

AttributeError: 'NoneType' object has no attribute 'byte_compile'
dpkg: error processing python-storm (--configure):
 subprocess post-installation script returned error exit status 1
Errors were encountered while processing:

E: Sub-process /usr/bin/dpkg returned an error code (1)

I tested it as an upgrade on a system with 0.14 installed, and as an install to a fresh system booted from a Live disk.

Note that, despite this error, the package does appear to install correctly (albeit in /usr/local/lib/... rather than in /usr/lib/...)
