Apple Mail, Photo Browser, Attachments and Yosemite

Question

OK,
Help. 
Anytime I want to insert a photo from my iPhoto Library into Apple Mail via Photo Browser in  Yosemite Mail, it crashes.
My preferred method - Via add attachments - Finder/Pictures/Iphoto library doesn't work anymore. It now says Open iPhoto library.
Why does Apple change these things without like checking them out?
Anyone have an advice. I think Yosemite is pretty half baked. I'm a computer consultant and this is the worst release for customers since Leopard.

Post the first 50 lines of the Mail crash report and the lines for the crashed thread.
As a test launch iPhoto with the Option key held down and create a new, test library.  Import some photos and test to see if the same problem persists. Does it?
Note:  Since it's Mail that's crashing it's not an iPhoto problem but a Mail/System one.
Log into another user account on your Mac and test to see if the problem persists there.  If it does then it's a system wide issue. If not it's an account issue.
Download and run Etrecheck.  Copy and paste the results into your reply. It's a diagnostic tool that was developed by one of the most respected users here in the ASC to help identify some of the more obvious culprits.
