Here also the GDB trace for the nomacs segfault. ** Attachment added: "GDB trace for the nomacs segfault" https://bugs.launchpad.net/ubuntu/+source/exiv2/+bug/2144804/+attachment/5953738/+files/nomacs.gdb.txt
** Description changed: Expected: Normal PNG and JPG images should open in gwenview and nomacs. Actual: After apt upgrade on 2026-03-18, gwenview and nomacs started segfaulting when opening images. Baloo File Extractor also appeared to crash when touching image files. What changed: apt upgrade changed libexiv2-27 from 0.27.2-8ubuntu2.7 to 0.27.2-8ubuntu2.7+esm1 on 2026-03-18 12:38:52. Evidence (segfaults): - - gwenview backtrace hits Exiv2::ExifData::begin() - - gwenview JPG backtrace hits Exiv2::Image::setMetadata() + - gwenview (opening PNG) backtrace hits Exiv2::ExifData::begin() + - gwenview (opening JPG) backtrace hits Exiv2::Image::setMetadata() - nomacs backtrace also hits Exiv2::Image::setMetadata() Confirmation: Downgrading libexiv2-27 back to 0.27.2-8ubuntu2.7 immediately restored normal PNG and JPG opening in both gwenview and nomacs. Relevant package history: - 2026-03-18 12:38:52 apt upgrade upgraded libexiv2-27 from 0.27.2-8ubuntu2.7 to 0.27.2-8ubuntu2.7+esm1 - Reinstalling the same versions did not help - Downgrading fixed the issue $ lsb_release -rd Description: Ubuntu 20.04.6 LTS Release: 20.04 Reporting the bug using Apport/ubuntu-bug did not work for me. Not being able to open any images on a system is quite a serious limitation/consequence. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2144804 Title: libexiv2-27 0.27.2-8ubuntu2.7+esm1 causes gwenview and nomacs to segfault when opening normal images on Ubuntu 20.04; downgrade to 0.27.2-8ubuntu2.7 fixes it To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/exiv2/+bug/2144804/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
