Digikam wasn't open and I understand (now) that this isn't supposed to be done. When digikam was opened it crashed immediately. I removed the database files and tried again, same. I reinstalled and removed the database files and tried again, same. I did the above step and removed the digikamrc file in .config, same. I tried to set up a different folder with different pictures for the digikam gallery but same. STEPS TO REPRODUCE 1. Move and/or rename subfolders in Digikam managed folder externally (without digikam being open). 2. Open Digikam OBSERVED RESULT Whenever digikam opens the UI appears but is not interactive and digikam crashes after a moment. Below is the terminal output from starting digikam. $ digikam ALSA lib pcm_dsnoop.c:567:(snd_pcm_dsnoop_open) unable to open slave ALSA lib pcm_dmix.c:1000:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm.c:2721:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear ALSA lib pcm.c:2721:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe ALSA lib pcm.c:2721:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side Cannot connect to server socket err = No such file or directory Cannot connect to server request channel jack server is not running or cannot be started JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock Cannot connect to server socket err = No such file or directory Cannot connect to server request channel jack server is not running or cannot be started JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock ALSA lib pcm_oss.c:397:(_snd_pcm_oss_open) Cannot open device /dev/dsp ALSA lib pcm_oss.c:397:(_snd_pcm_oss_open) Cannot open device /dev/dsp ALSA lib pcm_a52.c:1001:(_snd_pcm_a52_open) a52 is only for playback ALSA lib confmisc.c:160:(snd_config_get_card) Invalid field card ALSA lib pcm_usb_stream.c:482:(_snd_pcm_usb_stream_open) Invalid card 'card' ALSA lib confmisc.c:160:(snd_config_get_card) Invalid field card ALSA lib pcm_usb_stream.c:482:(_snd_pcm_usb_stream_open) Invalid card 'card' ALSA lib pcm_dmix.c:1000:(snd_pcm_dmix_open) unable to open slave Cannot connect to server socket err = No such file or directory Cannot connect to server request channel jack server is not running or cannot be started JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock kf.xmlgui: Unhandled container to remove : Digikam::DigikamApp Segmentation fault (core dumped) EXPECTED RESULT No crash, or no crash after reinstalling Digikam SOFTWARE/OS VERSIONS Ubuntu 24.04.4 LTS Gnome Version 46 X11 Linux 6.17.0-19-generic ADDITIONAL INFORMATION Here is the backtrace (I tried to install all packages for debug symbols, but some seem to be missing): Thread 7 "Digikam::ScanCo" received signal SIGSEGV, Segmentation fault.
