Title:
  nautilus crashed with SIGSEGV in nautilus_files_view_set_selection
  when working with large directory tree

Status in Nautilus:
  Fix Released
Status in nautilus package in Ubuntu:
  Fix Released
Status in nautilus source package in Noble:
  Fix Released

Bug description:
  [ Impact ]

  Was working with a relatively large directory tree (machine learning
  dataset of images, separated into folders). Nautilus froze up and
  crashed. Unsure if it's related to the large directory tree but I have
  found it getting sluggish in similar places

  There are multiple crash reports of users doing different things when
  it crashed, but one has a consistent reproducer that matches the same
  stacktrace. We will use this in the test plan.

  
  [ Test Plan ]

  1. Open the "Files" app (nautilus)
  2. Select two files
  3. Right click to open the context menu
  4. Click "Open With..."
  5. Select the "Files" app
  6. Click "Open"
  7. Verify that nautilus did not crash
  8. Verify that nautilus is showing the directory containing the two files

  [ Where problems could occur ]

  This fix is being included in the 46.4 SRU: bug 2108849
