[Bug 1941752] [NEW] Regression: exiv2 0.27.3-3ubuntu1.5 makes Gwenview crash when opening images exported by darktable

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Ubuntu Foundations Team Bug Bot (crichton):

Since the recent security update of exiv2, Gwenview crashes when trying
to open image files that got exported by darktable.

Steps to reproduce:

* Make a test installation of Kubuntu 21.04 in VirtualBox
* Install all updates
* Install darktable
* Copy one of the images in /usr/share/wallpapers (or any other image) to your home directory and open it with darktable
* Within darktable, export a copy of the image (no need to do any actual modifications)
* Try to open that copy with Gwenview. Gwenview will crash.

I'm attaching a crash report hinting that this is related to exiv2.

Temporary workaround:
If I downgrade libexiv2-27 to 0.27.3-3ubuntu1.4, Gwenview doesn't crash, so it seems the crash is related to changes in 0.27.3-3ubuntu1.5.

I don't know if the underlying cause is actually some bug in exiv2,
Gwenview or darktable.

Kind regards, Jan
