in 2.28.4, dragging a file to evolution composer automatically expands the attachment bar and attaches the file. in 2.30.0, dragging a file pastes its path as text and I drag it directly to the attachment bar, evo crashes f 1 #1 0x00007fffea2cabf9 in webkit_editor_drag_data_received_cb ( widget=0x555556aae230, context=0x555555989920, x=0, y=0, selection=0x7fffffffdf40, info=6, time=4772764) at /home/hussam/cache/system/gnome/evolution/src/evolution/src/modules/webkit-editor/e-webkit-editor.c:5082 5082 if (!GTK_WIDGET_CLASS (e_webkit_editor_parent_class)->drag_drop (widget, context, x, y, time)) {
This seems to be caused by a change in WebKitGTK, because the crash cannot be reproduced with 2.28.4, but can be reproduced with 2.30.0. The steps are like this: a) open evolution composer, can be like this: evolution mailto:a@b.c b) open nautilus and drag a file into the message body - if it lets you (the cursor is with "+"), then the drop will paste the file path into the body; it doesn't crash yet. c) drag the same file from the nautilus, but this time drag it above the body, then up above the headers (To/Cc/...) after which the application crashes.

After a bit more debugging the `GTK_WIDGET_CLASS (e_webkit_editor_parent_class)->drag_drop` is NULL. It splits this bug into two pieces: 1) make sure evolution doesn't dereference NULL here 2) WebKitGTK should not accept the file as a text input for the WebView content
(In reply to Milan Crha from comment #2) > 1) make sure evolution doesn't dereference NULL here Done with [1] for 3.39.1+ and 3.38.1+. [1] https://gitlab.gnome.org/GNOME/evolution/commit/6ad8626d93
I think this is a duplicate of #218562. The problem is that we were not allowing evo to handle the drop. *** This bug has been marked as a duplicate of bug 218562 ***
I agree, it might be the same thing.
(In reply to Milan Crha from comment #5) > I agree, it might be the same thing. Indeed it is. It is fixed in 2.30.3 Milan, please CC me when filing webkit bugs that effect evolution so I can time local updates. Thank you!
