Comment 7 for bug 406245

Dear release team,

This bug has been pending sponsorship since before FeatureFreeze. The current upstream version of Subversion in Karmic is 1.6.1, fairly early on in the lifetime of the 1.6.x series. This merge would see it brounght up to 1.6.5, incorporating many upstream bugfixes and at least one upstream security fix. I think it would ultimately more useful and more maintainable to see Karmic released with a newer upstream version rather than putting work into backporting the security fix and whatever handful of bugfixes are problematic enough to be bothered with.

Obviously this needs to happed sooner rather than later, since it's a fairly big change, but as we're currently only hours after FeatureFreeze I hope this exception can be considered reasonable.

I am including the relevant upstream change summary:
