Firefox update out, but there is a bug

From Ars Technica, version 1.0.1 of Firefox is out, fixing a curious previously known bug:

That particular bug results from Firefox's implement of the IDN specification which allows the use of non-English characters in URL names. So substituting the "a" in amazon.com with а will result in Firefox displaying "аmazon.com" in the address bar, while directing users to an entirely different site. The IDN issue is not unique to Firefox, as it also affects Opera, Safari, and OmniWeb — but not Internet Explorer.

Unfortunately 1.0.1 comes with a bug of its own:

Based on the reactions of some early adopters, 1.0.1 could have used a little more quality assurance testing before its release. The primary problem that is affecting multiple users is Firefox 1.0.1 crashing when a user types a query into a search bar, a rather irritating bug that should have been caught. It seems to affect most those people who installed 1.0.1 on top of 1.0. One solution is uninstalling 1.0 and then installing 1.0.1...

Now the brief review did go on to note that "according to Bugzilla, that bug has since been fixed"; but I couldn't quite get a fix on the last part. I'm holding off until the situation becomes clearer.
