Created attachment 144412 [details] draw-copyPage.odg: 4 pages with images Edited images (saved in /tmp/*.png) using GIMP, Pinta, or Shotwell result in a broken link instead of an edited image. However, if the /tmp/*.png image is round-tripped by Gnome image viewer, then the image re-appears in Draw. Also, I noted that the "broken" tmp file can be used to successfully replace an image, so LO is able to handle that image in general, but just not as a replacement during the "edit with external tool" process. Tested with Ubuntu 16.04 and 18.04 with 6.0 alpha and 6.2 master.
Confirmed based on bug 103455 comment 5.
bibisect-linux-dbg-51 shows this worked until the day of https://cgit.freedesktop.org/libreoffice/core/log/?qt=range&q=782c116b5ac39aef27c3a00f7fc145c9f755e3a3..c8344322a7af75b84dd3ca8f78b05543a976dfd5 In this range we see another idle bug (see bug 103455)! Suspicious, although I don't know how to reconcile that with being able to "fix" the problem by replacing the /tmp/png with a "good" image or using gnome-viewer. author Michael Meeks commit 48c2815dd20cf20eeec8bb4e003000f4a3d13291 (patch) tdf#91727 - Unwind non-dispatch of idle handlers. Comments suggest that Michael's patch is only for Linux. Can someone test to see if this external editing problem can be seen in Windows (although I don't know which applications to test with since even in Linux at least one application is known to work...)
Adding regression and bibisected keywords...
jmux just did some timing patches, but those have not resolved this issue.
*** Bug 120723 has been marked as a duplicate of this bug. ***
confirmed still broken in 7.0 master
confirmed (with gimp) still broken in 7.3+
Hit the same bug in current stable of Writer in Fedora 34. LIbreOffice Draw and Gimp being the editors, both time the image returns as a "Read Error" into LibreOffice!
It worked most of the time for me today. I was bibisecting in 7.3 and it seemed like I was narrowing down to a specific commit. But then when I went back previously non-working commits, then they were working. Then I checked out oldest of 7.3 and it worked too. So not sure what is going on here. Using Gimp and Ubuntu 20.04 still.
