DB2 9.7.1, db2start and SQL1042C

As you may know I'm running Kubuntu 9.10.
The other day I installed DB2 Express-C 9.7.1 on it. When I tried db2start I got:
SQL1042C An unexpected system error occurred. SQLSTATE=58004

If you get the same try running db2ftok and then db2start again. It works for me.
