Comment 1 Peter Penz 2012-02-03 19:38:02 UTC 
Thanks for the report, I could reproduce the issue.

Internal notes:
1. The breadcrumb must shown an URL with a parent (>)
2. Drag an item above > (-> menu X opens)
3. Drop above an item from the menu
4. Press Cancel
5. Click on view to close menu X
6. Repeat step 2 -> crash

Git commit 669ee3250d233b96bc2f2e63865b048d33215674 by Frank Reininghaus.
Committed on 02/07/2013 at 17:27.
Pushed by freininghaus into branch 'master'.

Fix crash when dropping URLs on the URL navigator's drop down menus

The problem was that the files were copied/moved inside the nested event
loop of the drag, which caused problems if the "File exists" dialog was
shown.

The solution is to make the copy/move operation delayed, such that it is
executed in the main event loop.

Note that dropping files on these menus does apparently not work at the
moment when using the Oxygen style (see bug 310016).
