This is something that has been happening to me for some days now, and it's very annoying! In this video you see that I "drag" the tabs, but I'm not intentionally dragging them, I just click on them to surf the site but Chrome 0.4.154.25 attaches the tab to my mouse and so it makes me drag them (there's nothing wrong with my mouse, I've tested it). The crash happens when this bugged dragging occurs and I move the tab along the tabs bar, when I release the tab Chrome gets confused or something because as you can see around minute 1:25 the CNET tab disappears and the NISSAN tab adopts the CNET URL. Well, Im not sure what really happens, but Ive tried reinstalling and deleting all history/cache/cookies/etc and it still happens. If you know how to fix this, I would like to hear it!

I recorded a video, so you can see what do I mean with all the text above:
