New crash information added by DrKonqi

gwenview (20.12.3) using Qt 5.15.2

- What I was doing when the application crashed:

This is a little bizarre. I encountered this while rapidly scrolling
through thumbnails in a directory. One particular image reliably crashes
QwenView, but it isn't the image itself because QwenView opens the image
just fine if I copy it to another directory. If I copy just a few of the
images to another directory, QwenView also works just fine. The
directory contents are available online to replicate this issue. I
downloaded and replicated again just to be sure.

The directory contents are available online inside this archive:
https://downloads.open-
tx.org/2.3/release/sdcard/opentx-t16/sdcard-480x272-2.3V0025.zip. The
directory is IMAGES. The image QwenView crashes on is IMAGES/P51.jpg.

To replicate, extract the archive, and start clicking through the
images. I double clicked on in Dolphin to start.

The crash can be reproduced every time.

Title:
  Regression: exiv2 0.27.3-3ubuntu1.5 makes Gwenview crash when opening
  images exported by darktable

Status in Gwenview:
  Unknown
Status in exiv2 package in Ubuntu:
  Confirmed
Status in gwenview package in Ubuntu:
  Confirmed

Bug description:
  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
