Bug description

There is a minor bug that is causing Nemo to crash when selecting some options (like Properties) of the right-click menu (context menu) when clicking on the empty space of the Tree View of the Sidebar.

Steps to reproduce

• View > Sidebar > Show sidebar (F9)
• View > Sidebar > Tree
• Right-clicking an empty space below the normal entries (Home, Favorties, File system, etc.) to open the context menu
• Clicking on some options (like Properties, Open) will cause Nemo to crash
• Some other options don't cause it to crash (like Eject, Copy, etc.)
• Reproducible on Live image (linuxmint-22.3-cinnamon-64bit.iso)

StackTrace.txt

Expected behavior

The action shouldn't result in a crash. The click should be ignored or the options on the menu shouldn't be displayed if they don't apply (since it's an empty space that is being right-clicked).

Additional information

Somewhat similar to #3640

Start by reproducing the crash in Nemo using the listed sidebar and Tree view steps, then inspect StackTrace.txt to identify the failing path. Verify that right-clicking empty Tree view space and choosing actions such as Properties or Open no longer crashes, while applicable menu behavior remains correct.
