I'm using Premier Pro CC on Yosemite 10.10.1. For some reason, whenever I attempt to drag a clip into a timeline — any clip in any project, new or old — Premier immediately crashes and I get an error: "Sorry, a serious error has occurred. Adobe Premier must shut down. We will attempt to save your project."
Here's the last crash report I got: gist:ebb14b58a932ff05a627
Obviously, I can't get any work done at this point, so I would greatly appreciate any help in trying to resolve this issue.

No solution thus far—in my case I had to reinstall Mavericks as Premiere had become unusable in Yosemite.
I was also experiencing crashes in Illustrator. I found my way to this thread and discovered that my problem is a Chrome extension called Pushbullet. After removing Pushbullet from Chrome and restarting my computer, I was able to drag clips in my timeline again. If you are using Pushbullet or perhaps another poorly executed Chrome extension, chances are, that could very well be the source of your problem!
