On my 7.1.3 on Unbuntu 10.04 64 bit (upgraded from 7.1.2 - 7.1.1 - 6.0.12) autocomplete from gal is not working, so I tried to force a gal sync from command line but I receive a NullPointerException

zmprov syg domain
ERROR: service.FAILURE (system failure: java.lang.NullPointerException)

The GAL is configured as internal.
Can you help me ?

thank you
