[2.2.2] Error when creating a .msi installer

[juan....@reduc.edu.cu]

Hello. I am trying to create a Windows installer with the SBT Native
Packager but I get this error:

[info] D:\git-repos\bringer\target\windows\Bringer.wix(1046) : error
LGHT0130 :
The primary key
'shortcut_190b8257_6992_49e7_9be3_40fd2513a201201020374_SC' is
duplicated in table 'Shortcut'. Please remove one of the entries or
rename a part of the primary key to avoid the collision.

I have never used Wix before, but openig the file mentioned above I saw
the problem is that I have the same key for "application.conf" and
"messages.es" files. I deleted the "messages.es" file and the problem
got fixed, no more duplicated IDs, but it was just a workaround and the
problem is still there. I would really like to have my "messages.es"
back without crashing the build sistem ;) What could I do? This looks
like a bug.
