yes, exactly. 1/ Exiv2 video support is turned off. 2/ The crash come from Exiv2. But i think it's normal. Exiv2 will generate a C++ exception if video file try to be loaded. As video support is disable, and as with gdb, we catch all C++ exceptions, gdb stop the execution when mp4 is parsed by Exiv2. So this behavior is normal for me. It's not a crash. It's a simple C++ exception throw by gdb. Does it crash without "debug" argument on command line ? Gilles Caulier Note : in gdb prompt, you must be able to continue to run digiKam with "c" command.

There is no problem here, no amount of updating will stop it. As Gilles wrote in comment #6 the debug mode of the AppImage enables catching of exceptions being thrown, even if they are handled. This means the execution is paused (not aborted) and you get to the gdb command prompt. You can resume by entering "c" and pressing Enter. If you don't want execution to be paused on thrown exceptions, you can enter info breakpoints delete *num* where *num* is the number of the line containing exception throw.

Simon, Thanks for your reply. I just don't get why it behaves differently on OpenSUSE where I don't have to press see after trying to generate a thumbnail for every single mp4 file. Basically I cannot debug digiKam on Linux Mint bacause I have mp4 video files in each folder. On OpenSUSE you use the AppImage as well? And you can debug without having to press a button for every mp4 file, just use the workaround I gave in comment #8. I am however curious about the reason why "catch throw" is activated automatically in AppImage (@Gilles). Well, Marcel recommend to catch C++ exception to handle all problems report by Exiv2. Of course we can disabling this behavior now. Gilles Git commit 8d0da94bc711c374d491b85678484147af8edc5f by Gilles Caulier. Committed on 27/08/2017 at 12:27.

Hello, I tried appimage on Mint MATE and it works just fine but if I launch it with 'debug' option it crashes on startup. See bugtraces below. It looks like it the same ol' story with exiv2 and mp4 files but I thought the video file metadata support was turned off awhile ago...
