I was hoping someone would have already bounced this thread, but I guess not.
There is a confirmed bug in JOSM 2417 that breaks uploading, and may encourage users to inadvertently delete ways if the validator plugin is installed. It looks like there's a partial fix in 2439SVN, but the root problem may not be completely fixed yet. Please see http://josm.openstreetmap.de/ticket/3884 for the gory details. I've not sure which group handles it, but I'd recommend at least adding a note to the MOTD. If anyone else thinks it's critical enough, then it might be necessary to set the server to blacklist any edits that come from 2417 as well.

I have it when downloading small areas along my GPS tracks. A lot of ways come in "empty" (with 0 nodes) which causes problems later for the validator and when trying to upload my work.
