Comment 3 for bug 637131

ScottK: it's a years-worth of incremental glyph adjustments to the font itself. Since this is a font, the risk introduced (compared to incremental code is low). It would be possible to cherrypick the actual /etc/fonts/ configuration files (with the pattern matching at stake here) if required but there are maintenance advantages to going with the Debian version that there is an active upstream who is engaged and already responsive to the Ubuntu bugs directly.
