gnumeric-gtk has unexpected linefeed in /usr/lib/mime/packages/gnumeric-gtk

Binary package hint: gnumeric-gtk

The contents of /usr/lib/mime/packages/gnumeric-gtk gets added to /etc/mailcap (I don't know how or when), most applications handle the linefeed without issue. However, pgadmin3 points out the error in /etc/mailcap.

The issue is the linefeed on about line 22 of /usr/lib/mime/packages/gnumeric-gtk where a space has become a linefeed. Of course, removing the linefeed in /etc/mailcap prevents pgadmin3 from reporting the error. Removing the linefeed from /usr/lib/mime/packages/gnumeric-gtk should alleviate the problem for good.
Here's a copy of the file as it existed on my computer:
