Hi,

As much as I would appreciate this being solved in Jessie, I have now
documented Daniel's (i.e. dkg's) work around in the release-notes under
"Issues to be aware of for Jessie".  Note that the website might be 4-6
hours before it generates the new version, so you might not see it yet
in the live version.

Should you find/device a patch for it in time for Jessie, I am happy to
review it from an RT PoV.

Thanks,
~Niels
