In order to reproduce the bug:
 Create a text document and insert some drawings objects. Menu: Insert > Form > ...
 Save document.
 Change edit mode to read-only: Menu: Edit > Edit Mode
 Display Find toolbar.
 In drop-down menu “Navigate By” try to select Drawing. A selection in this menu is not possible. Expected: A Selection and afterwards a navigation should be possible also in read-only mode, like it is possible for text searches in the same toolbar.
Hi Harald a patch for this was merged.
