[Robert D.]

Package: reportbug
Version: 6.4.4
Severity: important

Dear Maintainer,
After entering the package name and clicking continue, the GTK version of reportbug crashes with the following:
Traceback (most recent call last):
  File "/usr/bin/reportbug", line 2206, in <module>
    main()
  File "/usr/bin/reportbug", line 1080, in main
    return iface.user_interface()
  File "/usr/bin/reportbug", line 1702, in user_interface
    latest_first=self.options.latest_first)
  File "/usr/lib/pymodules/python2.7/reportbug/ui/gtk2_ui.py", line 1498, in func
    args, kwargs = op.sync_pre_operation (*args, **kwargs)
TypeError: 'NoneType' object is not iterable

Thanks,
Robert
