It's worth mentioning both that Debian Testing is not called 'stable' because, in their own words, there are occasional significant breakages. It's also worth mentioning that right now, Debian Testing is being prepped for a freeze to become Debian Stable in less than a month, and it's absolutely chaotic as everyone is applying patches all over the place to get them in before the freeze.
After the freeze there'll be two months to sort out critical bugs like the ones in the article, but this possibly wasn't the best time to do a big upgrade of an edge-case system. Well, unless you want to find and report bugs :)

No, it's not. That said, if you want to run Debian testing, do yourself a favour and also install apt-listbugs -- it'll hook into apt, and alert if the update has any bugs filed against it (the update you are installing, that is).
I recently moved my laptop from Debian/stable w/backports to Jessie (testing) -- and it's been fine (had to do a reinstall anyway due to shifting around partitions, because I needed more space for windows so I could create an installer for windows 8.1 -- didn't have enough free space to ... don't get me started).
