SUMMARY: Previously, folders not owned by the user were fully accessible via Dolphin if the user had group membership and permissions. This version of Dolphin appears to disregard group permissions when the user is not the owner.

STEPS TO REPRODUCE
1. Create a folder not owned by your user but with any group your user belongs to.
2. Set permissions of the folder to drwxrwxr_x.
3. Open Dolphin and right-click on the folder to open the context menu 

OBSERVED RESULT
Notice that these three menu options are grayed out: "Create New", "Duplicate Here", and "Compress".
The same results are observed when entering the test folder and right-clicking on the empty space.

NOTE: I can drag and drop items into the un-owned folder but the associated mouse cursor shows "not permitted" symbol (red circle with line through it).

EXPECTED RESULT
If the user has group access to a folder the menu options should all be available as they were in previous versions of Dolphin.
