Mdworker32 quit unexpectedly with avenir_md plug-in

Question

Brand new MacBook Pro Retina 15 top of the line latest model with nothing running as I let it do a new Time Machine backup.
I checked in on it and found an interesting error message that neither Bing nor Google has ever indexed...
"mdworker32 quit unexpectedly while using the avenir_md plug-in."
Seems to be related to Story Mill, but just wanted to share this here if others have seen this error.

Answer 1

I got now already several times a similar error message:
mdworker32 quit unexpectedly while using the Microsoft Office plug-in
(the head of the error report is pasted in below)
The problem did show up after I updated my system yesterday from 10.8.5 to 10.9.1.
Office 2011 is at 14.3.9, which seems to be the latest version.
Question:
Is it save to delete this file:
/Library/Spotlight/Microsoft Office.mdimporter?
Or parts of its Contents?
