Bug Report: nemo-desktop SIGSEGV in actions_changed (nemo-blank-desktop-window.c:282) #3660
Description
Distribution
Ubuntu 24.04 (Noble Numbat) / Linux Mint
Package version
nemo 6.4.5
Frequency
Only occasionally
Bug description
A segmentation fault occurs in nemo-desktop when file change signals are emitted. The crash appears to be a null pointer dereference in the actions_changed function, triggered during a directory refresh cycle.
Signal: SIGSEGV (Signal 11)
Location: ../src/nemo-blank-desktop-window.c:282
Function: actions_changed
Context: The crash is triggered by nemo_directory_emit_files_changed. It appears that while updating desktop actions in response to file changes, the process attempts to access an invalid memory address (_tag_ptr was reported at 0x20 in the local frame).

Steps to reproduce
i believe i was installing/updating repositories. Or even due to external drive that was inserted
Expected behavior
The desktop manager should refresh icon states and context menu actions seamlessly when file changes are detected, without crashing or dereferencing null pointers.
