Description of problem:
Can't drag and drop file attachments to evolution mail composer when composer is started from the main mail reader by New. Instead attaching the file, its file:// link is inserted in the mail text regardless where it is dropped: mail text field or attachment bar.

When attempting to "attach" a second file, evolution crashes while the second attachment yet hovers above the composer window but before it is actually dropped: dumps core on FC32 and severely hangs on FC33, blocking the whole desktop so that I had to switch to a terminal, log in and kill -9 both evolution and file browser (caja).

Drag and drop mostly works in a standalone composer: dragging file to attachmnet bar produces an attachment, and dragging it to text field produces the file:// link, no crashes.  Mostly means that some files are not accepted by the composer but I was not able to make out any particular pattern.
