syncpackage reports wrong url for 404

[Barry Warsaw]

$ syncpackage -d sid pylint
syncpackage: Source pylint -> precise/Release: current version 0.24.0-1, new version 0.25.0-1
Unable to connect to http://packages.debian.org/: HTTP Error 404: Not Found
Traceback (most recent call last):
  File "/usr/bin/syncpackage", line 644, in <module>

  File "/usr/bin/syncpackage", line 368, in copy
    changes = get_debian_changelog(debian_spph, base_version).strip()
AttributeError: 'NoneType' object has no attribute 'strip'

So, one problem is that copy() can't handle None coming back from get_debian_changelog(). It should probably die more gracefully. The other problem is that the 404'ing url being complained about is not the actual url that it tried, so you don't really know what's failing.
