But it should. And don't blame me for that particular design. ;)

If the mysql database is structurally broken (gnunet-check can't see
that!) it is clear the insertion can't work properly - but gnunetd
may well think its ok if MySQL doesn't return failures on ops.

Thats easily seen by e.g. 'ps aux'. And besides, you probably
shouldn't run gnunetd as root. Create a fresh user for it or something.

No. database.list shouldn't be touched by hand.

It will not take up any extra space to reindex or reinsert - just time.

It shouldn't have fixed anything. The line is simply redundant.
The current code ignores it.

Your cc: list looks malformed. It doesn't have , in it between
my address and the gnunet-help@ -address. Maybe your email client
is having a bad day.
