At first it crashed when opening source.* file or switching to a source syntax, it was ok with .txt, .md and .html files.
I tried removing Global.tm_properties and ~/.tm_properties and it seemed to work, I was able to open some ruby files, but it crashed when opening .erb files.
I quickly tested 9303, it was the same. So I'm back to 9302 for now.
BTW, thanks to Allan and all the contributors for the steady work since the githubing of Textmate. Love it!
