--- Comment #14 from code@luigifab.fr code@luigifab.fr --- Thanks, yes, if Pango is updated for example from 1.41 to 1.45, the previous %post doesn't work. You are right, Fedora uses only Pango > 1.44, so I will do the sed commands in other way.
These changes are required because Pango 1.44 break the metacity theme. I will push the current version soon.
