Comment 9 for bug 1058764

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.
