From Chromium Project:
Steps to reproduce the problem:
1. Open Chrome.
2. Attempt to interact with the browser in any way.What is the expected behavior?
Browser should work.What went wrong?
The browser crashes completely on every start attempt.
After further investigation, it seems the crash happens when built-in Trackpad or Magic Trackpad is used to interact with Google Chrome on any Macs running OS X Yosemite 10.10.2 build 14C68k.

We’ll see if this issue would be resolved in the next build of OS X Yosemite 10.10.2 seed.
