xmms2 refuse to start with SQLite Error code 1

[pype]

I find myself for the 2nd time unable to launch xmms2d after it has stopped working. Restarting the daemon results in the following messages shown on the command line:
> INFO: ../src/xmms/log.c:49: Initialized logging system :)

~/.config/xmms2/medialib.db is present and reported by `file` tool as

log file is huge (~1GB) and contain entries such as the following:

medialib.db has grown up to 17GB, which looks excessive to me.

FYI, once compressed with gzip, medialib.db only needs 23MB of storage. I suspect repeated addition of dummy content in the DB (ie. "file x is missing" or "file y cannot be read because of a missing plug-in). How could I check for that ?
