Crashing on export

I managed to get indesign to crash when exporting a pdf by impatiently clicking on a layer as it was in the process of exporting. 

After several re-boots, several attempts of starting up Indesign and trying to recover/not recover and ignore recovery and waiting forever this to happen - I've come to the conclusion that the file I was working on cannot be opened and is beyond repair.

 But accidentally clicking on a layer mid-export really shouldn't be that catastrophic. I'd like to test it further, but I just want to move on.

I'm marking this a big, coz it certainly aint no feature. 🙂
