I've ran into an irritating error after migrating the data from one server to the other. One of my projects under Trac got corrupted. I've found the solution:

One of my trac page got the error message "database disk image is malformed" "underlying Trac DB is in serious trouble, may corrupted" - Ticket #6347 How I fix: [cc lang="bash" escaped="true"]sqlite3 trac.db .dump | sqlite3 trac2.db cp trac.db trac.broken.db cp trac2.db trac.db[/cc]

via Helmi Ble'be': Trac error - database disk image is malformed.
