Status changed to 'Confirmed' because the bug affects multiple users.

Just to add a piece of information, for me this is only happening on laptops I upgraded directly from 12.04 to 12.10. On a clean install, this bug does not happen.

[Marco Trevisan (Treviño) (3v1n0)]

Mh, it seems caused by the webapps, but I can't easily riproduce it nor I see evident issues on the codepath.

I hope to investigate further on it.

[Blaž Triglav (blaztriglav)]

Yes, in my case it is webapps as well, gmail is unusable, the error pops up after a minute or so of using it and the entire OS slows down to a crawl, menus stop working and at least a log-out/log-in or a restart is required to get the system operational again.

The vast majority of the time I don't even manage to send an error report because the OS just stops responding.
