If you are working with JavaScript, the last update to that bundle is causing TextMate to hang, if you have this issue, you can temporarily install the previous version using these steps:
cd ~/Library/Application\ Support/TextMate/Managed/Bundles rm -rf JavaScript.tmbundle git clone https://github.com/textmate/javascript.tmbundle.git JavaScript.tmbundle cd JavaScript.tmbundle git reset --hard 6046ce52330544d97ba9493c8dc56c7dcfcc6692
Sorry about the inconvenience.
