Duplicate Home bookmark when pressing Ctrl+D multiple times

Summary

Pressing Ctrl+D to bookmark the Home folder multiple times creates duplicate entries in ~/.config/gtk-3.0/bookmarks.

Steps to reproduce

1. Open Nemo and navigate to your home directory (/home/$USER)
2. Press Ctrl+D (Add Bookmark)
3. Press Ctrl+D again
4. Open ~/.config/gtk-3.0/bookmarks — you will see multiple lines for the same location

Example file content:

file:///home/r Home
file:///home/r Home
file:///home/r Home
file:///home/r r

Root cause

The duplicate check in nemo_bookmark_list_contains() (src/nemo-bookmark-list.c:421-424) uses nemo_bookmark_compare_with(), which compares both the URI and the display name.

When a bookmark is first created by nemo_window_add_bookmark_for_current_location(), its initial name is the basename of the path (e.g. "r" for /home/r). Shortly after, bookmark_set_name_from_ready_file() asynchronously renames it to "Home" because nemo_file_is_home() returns TRUE.

On the next Ctrl+D:

• The existing bookmark has name "Home"
• The new bookmark has name "r" (not yet renamed)
• nemo_bookmark_compare_with() sees "r" ≠ "Home" → reports not duplicate
• A second entry is appended

Proposed fix

In src/nemo-bookmark-list.c:423, change:

g_list_find_custom (bookmarks->list, (gpointer) bookmark, nemo_bookmark_compare_with)

to:

g_list_find_custom (bookmarks->list, (gpointer) bookmark, nemo_bookmark_compare_uris)

The function nemo_bookmark_compare_uris() already exists in libnemo-private/nemo-bookmark.c and compares only the URI. Bookmark identity should be based on location, not label.

Version

Nemo 6.6.3 (source 6.0.2 contains the same logic)

Start in src/nemo-bookmark-list.c at nemo_bookmark_list_contains(), especially the g_list_find_custom call around lines 421-424. Read nemo_bookmark_compare_uris() in libnemo-private/nemo-bookmark.c, then verify that pressing Ctrl+D repeatedly for the Home folder leaves only one URI entry in ~/.config/gtk-3.0/bookmarks.
