Bug 424618

Please start the AppImage in the terminal with the "debug" option and post the backtrace.

Maik

what is backtrace?

the text trace od debugger on the console. See details here :

https://www.digikam.org/contribute/

when I used gdb it said there was no bugs but when I just start digikam from the comand line I get 

Unhandled container to remove :  Digikam::DigikamApp

Sound like a lib problem used by Chromium browser (qtwebengine component in digiKam)

Gilles Caulier

it works without any porblems on 6.4.0 but when I downloaded 7.0.0 it stoped working.

DigiKam-6.4.0 still used QWebKit as browser engine. But for security reasons it shouldn't be used anymore because we also login to web services with the browser engine in the export tools.

The problem is related to libnss3.so.

Either you need a preload of the library or maybe this helps:

The workaround in comment 7 did not work for me, at least not as a copy+paste solution. I don't know anything about symbolic links.

Debian stable with AppImage 7.0.0

digiKam 7.0.0 stable release is now published:

We need a fresh feedback on this file using this version.

Thanks in advance

I don't understand. I did not use the RC version. I used the stable release.

AppImage: preload libnssutil3 to prevent crash with GoogleMaps and QtWebEngine

This is still happening in 7.1.0 appimage using Debian Buster:

This can fix your crash if you force to preload xcb-dri3 shared library before the appimage ?


env LD_PRELOAD="/usr/lib64/libxcb-dri3.so.0" ./digikam-7.1.0-x86-64.appimage

Can't edit my last reply, could some mod please redact my user name in Comment 16?

well no, it's not a wiki, comments still read only...

I am also experiencing this on Debian buster, or even a crash on start (us kernel.unprivileged_userns_clone=1).

Workaround:

./digikam-7.0.0-x86-64.appimage --appimage-extract
cd squashfs-root
find . -name '*nss*.so' -delete
edit AppRun, comment out "preload_shared_library libnss3.so"
cd ..
./appimagetool-x86_64.AppImage squashfs-root/ digikamtest.AppImage

appimagetool is from https://github.com/AppImage/AppImageKit/releases

So to summarize, for me, removing nss from the appimage fixes the issue.

7.2.0-beta1 appimage bundle are now build without libnss internally, and it available for testing at this url:

Can you reproduce the crash ?

Thanks in advance
