I am having the same issues with Dreamweaver crashing. I have a mac environment, it does the same thing using either my iMac or my MacBook Air both have the latest OS X10.9 Mavericks operating system and it will also do the same thing using Dreamweaver CC and CS6. I too have tried all the suggestions listed in your post.
I see you have had a number of private messages regarding this issue, did you manage to get the problem solved? It's becoming very frustrating.
