Mail crashes under OSX10.10

Question

Hi all,
after updating to OSX10.10 my mail programm crashes a lot.
I can replicated it with 100% "success" by clicking on the "sent"-folder.
All other folders work fine. It's always the sent-folder that makes it crashing.
I deleted my google mail account and installed it again - same thing.
Any ideas?
It's really annoying and I'm thinking about switching to a 3rd party mail client.
thanks in advance!
