Comment (by vanto):

 Replying to [[span(style=color: #FF0000, simonpj )]]\\
 I think you should wait a little.\\
 There is a contradiction to correct this without first correcting ticket
 {{{#9173}}}.
 On the other hand there is more to remove.\\
 See the comment n ° 2 that I wrote in the ticket {{{#13902}}}.
 Many people agree to review and improve the error messages. I think that
 this must be done in a collegial way and not punctually.\\
 This correction would be made once and for all and not a sudden blow.\\
