Hi. I use 64 arch fully updated with lxde and openbox. pcmanfm is 1.1.0-1 and libfm 1.1.0-3, both from arch's repo.
Drag and drop files to the Trash item in the left panel doesn't seem to work, nothing happens. However drag and drop between folders, tabs, bookmarks... work fine, the problem seems to be related only with Trash
