Had the same issue arise this evening. Had just bookmarked a site, setting it up to auto-refresh, and then it started barfing.
There is a way to clear the cache (Settings | browser | something) but that did not solve my problem.
Connected to the laptop and did an advanced restore and cleared the cache, bookmarks, etc and still no joy.
Am currently upgrading to 220.127.116.11 to see if that buys me anything.
If that does not work, the next step is a wipe w/ a selective restore until I barfs again so that I know what not to restore.... unless someone has a better idea.
