GIMP version: 18.104.22.168 commit 55977d84
Operating System: Linux, Fedora 28, GNOME
Package: from Git updated commit 55977d84
Description of the bug
Is not possible to add new tabs on the docks normally, they are being added only as header and, they are appearing as a blank dialog (when you try to close them).
Is the bug reproducible? Always
- Opens a separate dialog;
- Try adding another tab dialog < apparently is not added;
- Now, close the tabs of docked dialog < is possible to close any tab firstly added, but they are not shown the dialogs but only the headers.
