A disk full condition can break SDK configuration

Due to a runaway logging process, my SDK drive became full. Unaware of this, I started the updater, which came back with the error that it's unable to save the configuration because the disk is full (understandable). However, upon killing the runaway process and restarting QtCreator and the updater, it seems that the update attempt (or the creator restart) has actually damaged my package install info. I would recommend some sort of atomic write-rename to avoid this kind of behavior (or at least a non-destructive graceful fail). My post-mortem components.xml has only
