Remark: With PDF2.0 the Metadata are not any longer stored in a dictionary but rather in a Stream object. While this is optional for PDF2.0 (ISO 32000, 14.3.3) it is mandatory when using UA2 (ISO 14289-2) that the Stream objects are used.

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.
