Two finger click causing crash

Every time I use a two finger click on the trackpad in the applications folder I get a crash message (http://i.imgur.com/aAb9y4K.png). It doesn't happen anywhere else in finder.

It asks whether I want to crash or continue but if I click continue then everything runs fine.

Any ideas please? Thanks for any help.

I'm using a 2012 rMBP fully updated. Reinstalling the OS didn't help.

Here's the error log:
