Crash with many tabs open

A global search and replace has left my editor with hundreds of open tabs. When trying to close them all from the File menu, the application crashes. When trying to close them one by one (by pressing Ctrl+W, no tabs are visible at that time) the application crashes as well. This happens every time.

The application crashes as soon as the tabs become visible again. Re-opening the application leaves it with the same tabs, so it's a question of time that it crashes again.

This happens on version 2.0.1, build 2217, on a MacBook Pro running Mac OS X 10.7.

It should also be noted that implementing this feature could very well solve the problem.
