for what it's worth, I've been able to use the chromium daily builds without any problems for about 6 months :)
I have been using the Chromium Ubuntu PPA for about 2 months and have had no issues until this week (details: http://code.google.com/p/chromium/issues/detail?id=29536 ).
Although crippling to Chromium on my machine, I am sure my newly encountered issues will be resolved shortly, so I am not worried.
Just thought that I would update - as of today's PPA update, the issue is resolved.
