It looks like a vessel in your save uses a part that contains a resource whose definition isn't installed.  Have you removed or updated any mods recently?  As with all bugs, a full output_log.txt file (uploaded to a file hosting site such as dropbox) may well give more clues as to which resource/mod is the problem...
