1930733 - [KDE] Drag and drop only adds first file

Status: RESOLVED DUPLICATE of bug 1908196

(Thunderbird :: OS Integration, defect)

Description

[pierre.sauter]

Attachment: moz_log_WidgetDrag5.txt

Steps to reproduce:

• compose new email
• select two (or more) files in the file manager (dolphin) and drag them into the compose window to attach to the email

Actual results:

only the first file of the selection (seems to always be sorted in some way, not dependent on selection order) is attached

Expected results:

all selected files should be attached

My version is 128.4.2esr, which has been updated recently, and that update seems to have introduced the bug.
This one seems related, but is not very specific:

I also found this thread on reddit about the exact same problem:

The logfile was created with MOZ_LOG="WidgetDrag:5" as requested in the other bug.

The following part seems relevant:

[Parent 63290: Main Thread]: D/WidgetDrag DragData() URI MIME text/uri-list
[Parent 63290: Main Thread]: D/WidgetDrag 0 URI file:///var/tmp/test1.txt
[Parent 63290: Main Thread]: D/WidgetDrag 1 URI file:///var/tmp/test2.txt
[Parent 63290: Main Thread]: D/WidgetDrag [D 1] text/uri-list received
[Parent 63290: Main Thread]: D/WidgetDrag DragData::Export() MIME application/x-moz-file index 0
[Parent 63290: Main Thread]: D/WidgetDrag export file file:///var/tmp/test1.txt (flavor: application/x-moz-file) as application/x-moz-file

The os is sending a list with two files, but only 1 is attached.
