oh, is it crashing because its trying to find blocks in "/home/igor/.bitcoin/blocks/blk*.dat" ?
thats not where they are

[duckartes]

I believe your db-dir isn't written properly.

"--db-dir ./db2" should be "--db-dir=./db2"

[romanz]

You should use --daemon-dir for specifying your bitcoind data directory.
It's set to ~/.bitcoin/ by default, so it looks for blk*.dat files at ~/.bitcoin/blocks/blk*.dat.
