[TxMt] Commands not working in recent TM2 builds

Dear all,

I have suddenly experienced wholesale failure of commands in recent builds of TextMate 2. I initially thought it was a bug in a nightly build, so I switched to normal releases and downgraded, but the latest normal release is also showing the problem. I believe I first saw it with r9367, but I can't be sure.

As far as I can tell, no menu actions (at least) are working. For example, in a LaTeX document, both pressing ⌘R or selecting "Typeset and View" from the menu does nothing. It's not just the LaTeX bundle either: selecting "View Scope" from the Bundle Development bundle also does nothing. My snippets seem OK though.

I don't really know where to start with figuring this out, so some help would be appreciated!

All the best, Jon
