[TxMt] ignore ".dSYM" folders?

Hey Everyone,

How can I ignore .dSYM folders? I've been fiddling with this for like an hour now and can't get the regular expression right in preferences. It's probably the most obvious thing in the world but it's eluding me.

This is my current folder ignore pattern

!.*/(.[^/]*|CVS|_darcs|_MTN|{arch}|blib|.*~.nib|.*.(framework|app|pbproj|pbxproj|xcode(proj)?|bundle))$

I've tried adding |.dSYM like this:

!.*/(.[^/]*|CVS|_darcs|_MTN|{arch}|blib|.*~.nib|.*.(framework|app|pbproj|pbxproj|xcode(proj)?|bundle)|.dSYM)$

And a couple other variations, but with no luck

Thanks for any help!
