eog does not save changes if image is rotated and flipped once

[Oliver Joos]

Binary package hint: eog

I use Ubuntu maverick 10.10 (release candidate) with eog 2.32.0-0ubuntu1.

1. open a jpeg image in eog
2. rotate it once (left or right)
3. flip it (vertically or horizontally)
4. save it explicitly or close eog and answer yes to save it
=> the image file is updated, but the image content did not change!

Further I saw:
- if rotating TWICE left or right and flipping once, it works as expected
- if rotating three times and then flipping is buggy like rotating once

it looks similar to bug https://bugzilla.gnome.org/show_bug.cgi?id=629960

[Oliver Joos (oliver-joos)]

Thanks, I read 629960: cause may be the same, but symptoms (and versions) are different. So I opened a new bug https://bugzilla.gnome.org/show_bug.cgi?id=632290 and mentioned there the similar bug. Perhaps both can be solved with the same fix.

A fix has been committed upstream!

+ Don't try to thumbnail named pipes in the file open dialog
+
+ In fact this means all "special" files like sockets and device files.
+ This prevents lockups due to file I/O blocking here. Fixes bug 623271.

+ Workaround concurrency issue with statusbar-date plugin
+
+ Make sure that only an image loading job does autorotation. A metadata
+ loading job has no use for this. Works around lost signals when the
+ statusbar-date plugin is activated. Works around bug 622161.

Fixed upstream long time ago.

As reporter of this bug I confirm that this bug is fixed - at least in Eye of MATE 1.12.0 of Linux Mint 17.3.
