Comment 9 for bug 37828

I reported this in Launchpad (the Ubuntu bug tracker) here:
    https://launchpad.net/distros/ubuntu/+source/firefox/+bug/37828

The conditions necessary to trigger it are:
 * using Pango for font rendering (the default with the Ubuntu Dapper packages).
 * using a font with ligatures (e.g. DejaVu Sans -- the default sans-serif
   font for Ubuntu Dapper).
 * using "text-align: justify" or equivalent markup to get justified text.

It seems that the ligature glyph is drawn, but the advance of standard glyph for the first character is used, resulting in later characters being rendered over the top of the ligature.

I am not sure if this is an Ubuntu-only bug yet. It would be interesting to hear if people not using Ubuntu are able to reproduce the bug, when the above conditions are met.
