As discussed in IRC it seems that the fact that some translations of .pot 
files that have 
"X-Qt-Contexts: true\n"
do not have them is more an artifact on how those files where created than 
what lokalize or other tools do so we've decided that we'll rely on 
"X-Qt-Contexts: true\n"
being present to decide if we have to convert it to .ts and .qm for installing 
or not.

Also a checker for scripty needs to be done to complain if a given .pot file 
has "X-Qt-Contexts: true\n" but a language one does not.

Aurelien do you think you can take care of both?

Cheers,
  Albert
