Merge lp:~pedronis/ubuntu-push/fixes-into-vivid into lp:ubuntu-push

[Samuele Pedroni]

* skip over Gone messaging notifications to address lp:1451510, eagerly identify them in Tags, tests
* truncate runtime.Stack result to size, otherwise we log \x00s or old stuff

bring in recent fixes into vivid overlay

[John Lenton (chipaca)]

Nice!

review: Approve

[Samuele Pedroni (pedronis)]

seems not to fix the problem enough (as tested by QA), just forget landing for now, don't revert code though because we think it's not worse/wrong
