Bug#649709: Please drop the gs-common Build-Dependency.
bacula-doc currently Build-Depends on gs-common, which is a transitional package.
The next upload of ghostscript (currently) plans to drop both gs-common and
the ghostscript "Provides: gs-common". As soon as that upload happens, it
will make bacula-doc FTBFS.
Please drop the Build-Depends on gs-common.
(The severity of this bug will be raised after the ghostscript upload.)
