Just wanted to add a short note firstly to confirm that workaround still works with the present state of Ubuntu development which is approaching the final freeze point.
The other part I wanted to mention is there in that same statement, the ubuntu release schedule is coming up quickly final release on 25th October, no idea where things stand for you or whether it would be an option for you in the development cycle to slip a patched version with the fix out prior to the release or just try and work around it for a time. Either way I wanted to give you a heads up on the status with ubuntu's popularity as a distro I suspect that you are likely to receive a number of support requests on this one come release day.
Heh, either that or somebody's hardware and software config will throw a fit at the upgrade for unknown reasons, I've been working on testing most of the betas though and the only other issue I've had affect second life was with the netfilter/iptables upgrades not too surprising given SL's reliance on a complex combination of protocols and dependence on multiple services, content providers and distribution systems to have everything working 100% what with the sims, caps/web services, voice, s3/cloudfront for maps not to mention arbitrary third party content providers for media SL tends to be very reliable at finding and highlighting any weakness in the local network stack or routing/reachability issues for sure.
Anyway, I guess you may already have been tracking the release schedule yourselves but in case you wern't just wanted to update you, link bellow has the complete timetable if it is of any use to you.
