mate-desktop-dbg 1.8.1+dfsg1-1 (armhf binary) in ubuntu utopic

 The MATE component mate-desktop contains the libmate-desktop library, the
 mate-about program, as well as some desktop-wide documents.
 .
 The libmate-desktop library provides an API shared by several applications
 on the desktop, but that cannot live in the platform for various
 reasons.
 .
 This package contains the debugging symbols for the mate-about executable.
 They are installed into /usr/lib/debug and will automatically be used
 by gdb.
