Red icon -- RandomFileInputstream read error

[magister]

Tonight MinimServer crashed. Everything was OK until I asked for a folder view, then the MinimWatch icon turned red and displayed the message quoted in the title of this thread.

I'm running update 33 and MinimStreamer 4.1 on a Synology DS213, DSM4 (whatever the last version of 4 is, I can't remember, but I didn't upgrade to 5).

I have not added any new music files for a couple of days, and played music extensively last night and earlier today.

Any ideas? Here's the log.
