MediaRemovalException when creating cockpitng-config

[aerrady]

Hi all,

I was trying to get my changes in custom-extension-backoffice-config.xml, but as I cannot see the update I removed the media config.xml, and login to backoffice, obviously it should assemble the media once again, but I'm getting lots of MediaRemovalException. Hereafter the beginning of the logs :
