From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; m18) Gecko/20001026 BuildID: 2000102608 trunk Reproducible: Always Steps to Reproduce: 1. Have enough bookmarks that the Bookmarks sidebar or the Manage Bookmarks window needs to scroll. 2. Open either the Manage Bookmarks window or the Bookmarks sidebar 3. Pick up a bookmark near the top of the list and try to drag it to the bottom by moving the mouse pointer past the bottom edge of the window (or just past the bottom edge of the pane with the bookmarks). Actual Results: Browser crashes Expected Results: Bookmarks scroll and allow you to drag the bookmark all the way to the bottom. This is a common operation. I think it needs to work for rtm.
