roundcubemail-0.2.2-2.fc11.noarch on F11. I have upgraded from F10 to F11, preserving the contents of the roundcube database, and users with the da_DK locale selected are now unable to log in to roundcube. After having entered their user name and password the browser (Firefox) displays a page saying Content Encoding Error The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression. The HTTP headers returned from the server look fine as they specify gzip as compression. Further requests to load the login page cause the same error page to be shown until the session cookie is manually deleted. This is 100% reproducible. Switching to the en_US locale by updating the language column in the users table makes the user able to log in again. This is apparently the exact same problem as discussed in http://trac.roundcube.net/ticket/1485928 , but removing the additional LF character from the end of messages.inc does not make the problem disappear.
