Description Gabor Kelemen (allotropia) 2025-08-03 10:50:51 UTC 
Created attachment 202157 [details]
Example file with many bookmarks

attachment 141424 [details] from bug 117066 contains about 1500 bookmarks, just like the attached file (but this is without 500 pages of actual content).

When all of these are selected in the Bookmark dialog and deleted, this takes more than a minute.

1. Open attachment 141424 [details] or the attachment here
2. Choose Insert -> Bookmarks
3. In the Bookmark dialog click into the list and select all bookmarks by pressing Ctrl-A
4. Press the Delete button
-> Writer becomes unresponsive for 15-20 seconds with my example. With the more complex attachment 141424 [details] it takes more than 10 minutes!
