A couple of points...
VIM crashed whenever I used the tab text expansion helper integrated with rails.vim (have I ever mentioned how much I love rails.vim integration!). Anyway, got the latest source for vim and recompiled and all is well on that front.
Firefox 3.0b5 - this is probably the biggest pita of the experience. I use Firefox as more of a developer tool these days then a regular browser. So, its all pimped up with my fav add-ons, extensions, etc. A few of which were not happy with Firefox 3.0b5. Here are a couple that come to mind being a problem:
- Firebug - fortunately the great folks here have an alpha 1.2 version that seems to be doing the trick for me
- Html Validator - I found posting somewhere (that now I can't seem to find again) that suggested libxul-dev would help. Which it did.
