We are trying to migrate from Interbase 6.0.1 to Firebird 1.5 on SuSE
linux 8.1.

When trying to restore the backup (about 4.5 GB), we get the following
error:

...
gbak: restoring privilege for user *****
gbak: creating indexes
gbak: restoring index RDB$PRIMARY77
gbak: restoring index RDB$PRIMARY73
gbak: restoring index RDB$PRIMARY65
gbak: restoring index RDB$72
gbak: restoring index RDB$PRIMARY62
gbak: cannot commit index RDB$PRIMARY61
gbak: ERROR: I/O error for file ""
gbak: ERROR: Error while trying to open file
gbak: ERROR: Permission denied
gbak: ERROR: action cancelled by trigger (3) to preserve data
integrity
gbak: ERROR: Cannot deactivate primary index
gbak: Exiting before completion due to errors

It seems that a file with name "" is being accessed (which of course
does not exist). The problem is reproducable and always happens at the
same spot during backup. Strange thing: restoring on a different
system with the same environment (or so it seems) does work! We did
the restore on that other system and then moved the DB. It works, but
while using the DB, we occasionally also get the above error during
queries.

Any help appreciated!
