Comment (by m.rick@…):

 I have discovered something very strange…
 My working installation suddenly stopped working giving me bug described
 here…
 I replaced the installation by the backup of the working one and it worked
 again! It's like something got corrupted inside. Is there any cache
 somewhere?
 I made a clean of the Mac OS caches system + users but it didn't correct
 anything, so i supposed it is something inside the installation path,
 isn't it?
