bat: symbol lookup error

Binary package hint: bacula

Description: Ubuntu lucid (development branch)
Release: 10.04

With bacula-console-qt 3.0.2-3ubuntu1 does not even start because of "bat: symbol lookup error: bat: undefined symbol: _ZN9QHashData13detach_helperEPFvPNS_4NodeEPvEPFvS1_Ei".

apt did not report any missing dependencies: all where satisfied.

looking with ldd I found:
