Locked by the message "A signed resource has been added, modified"

Hi Guys,

I'm in a trouble that makes me really nervous !!
For really no "good" reason, I'm having this message from XCode when trying to run & install my program on my device : "A signed resource has been added, modified, or deleted." !

To see where am I in my "nervousity", it's important to note that :
- My certificates worked well (application has been installed & executed previously several times without any problem AND just 1 minute before)
- The only thing I've changed in my program is a line of code I've commented (of course I've tried to uncomment it)
- I tried to clean project & rebuild, clean all targets & rebuilt, clear XCode cache, quit xcode, reboot my iphone, reboot my Mac, restart, rebuild
- I just tried to create new certificates from Apple, get it, install it on organizer, change my info.plist then rebuild, same problem
- I also tried to uncheck the "get-task-allow" from a "dist.plist" file I've added to the commitments,

Same problem...

I spent couple of hours, going through several forums, including this one, trying to find someone with the same problem (there's a lot) and trying to find the solution without success (I've tested everything found on the net for this problem).

What makes me creazy is that it happends really without any serious reason, my compilation worked just minutes before !!

Have someone some kind of help ?

Here are the errors from the console of my iPhone :
