Drag&Drop creates many identical temporary files
When dragging & dropping something from evolution (e.g., an attachment from a received e-mail or an e-mail itself), Evolution creates a folder containing the dragged item in /tmp
when hovering a drop target. Unfortunately, the folder and file is created repeatedly when new drop targets are hovered. The folders/files are not removed after dragging & dropping is done or canceled.
An extreme case is dragging & dropping to dolphin, where even the slightest move of the mouse over the dolphin window induces creation of a new folder/file, which can quickly produce hundreds of them.
I currently use Evolution 3.44.2-1 on Arch Linux.
