Please try to improve the quality of the backtrace by installing the
debug packages for libexiv2 (and possibly gwenview) and providing more
lines of output

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

2021-12-30 Thread simonschmeisser 
This is a debdiff applicable for focal-security. This backports an
upstream fix for the regression introduced when fixing CVE-2021-37620. I
build it locally in pbuilder and it fixes the crash in gwenview as
expected.

** Patch added: "1-0.27.2-8ubuntu2.7.debdiff"

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

Status in Gwenview:
  Fix Released
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
