Comment 1 Friedrich W. H. Kossebau 2019-08-11 17:39:02 UTC 
Git commit 4e0b20cd8b36814527331a3e62513377304dd05e by Friedrich W. H. Kossebau.
Committed on 11/08/2019 at 17:38.
Pushed by kossebau into branch '5.4'.

Fix crash: add missing Q_INTERFACES to OktetaDocument for IDocument

Some places rely on this being properly set due to using qobject_cast
for quick cross-casting.
FIXED-IN: 5.4.1
