In both cases rsyncing ~/.config/google-chrome from the last hourly snapshot has fixed the problem every time. Given that, I would say that google-chrome does not have a bug of half unclean states since the state present in a snapshot has always worked for me, but that's anecdotal, not proof. But if my kernel hangs due to a bug that isn't btrfs' fault and I need to power off and back on, after reboot my google-chrome profile is almost always broken in some way. This with a samsung evo 840 SSD which I believe does reasonable enough things on power shutdowns, although I can't prove that. File formats are some kind of raw data and sqlite 3.x ~/.config/google-chrome-beta/Profile 1: Last Session: data Last Tabs: data Login Data: SQLite 3.x database Marc -- "A mouse is a device used to point at the xterm you want to type in" - A.S.R.
