On OS X 10.9.2 I got a message in /var/log/system.log like
Google Chrome Helper: CoreText CopyFontsForRequest received mig IPC error (FFFFFECC) from font server
whenever I opened a new Chrome window. (running version 34.0.1847.131)
Fixing this was surprisingly easy:
1) open Font book
3) Validate Fonts from the file menu.
Once I cleared the problematic ones the messages no longer appeared.
