After being prompted for confirmation because of locale mismatch (see bug 382362) and cancelling, a segfaults occurs. I'm using digiKam 5.6.0 appimage build on Debian Stretch. This is what the appimage build displays on console: ``` $ digikam-5.6.0-01-x86-64.appimage -- digiKam AppImage Bundle -- Use 'help' as CLI argument to know all available options digikam.widgets: Breeze icons ressource file found digikam.general: AlbumWatch use QFileSystemWatcher digikam.general: Database Parameters: Type: "QMYSQL" DB Core Name: "XXXXXXXXXXXXXXXXXXXXX" DB Thumbs Name: "XXXXXXXXXXXXXXXXXXXXX" DB Face Name: "XXXXXXXXXXXXXXXXXXXXX" Connect Options: "" Host Name: "XXXXXXXXXXXXXXXXXXXXX" Host port: 3306 Internal Server: false Internal Server Path: "" Internal Server Serv Cmd: "" Internal Server Init Cmd: "" Username: "XXXXXXXXXXXXXXXXXXXXX" Password: "XXXXXXXXXXXXXXXXXXXXX" digikam.dbengine: Loading SQL code from config file "/tmp/.mount_9UXxlv/usr/share/digikam/database/dbconfig.xml" digikam.dbengine: Checking XML version ID => expected: 3 found: 3 digikam.coredb: Core database: running schema update digikam.coredb: Core database: have a structure version 8 digikam.coredb: Core database: makeUpdates 8 to 8 digikam.database: Creating new Location "/" uuid "networkshareid:?mountpath=//XXXXXXXXXXXXXXXXXXXXX" digikam.database: location for "//XXXXXXXXXXXXXXXXXXXXX" is available false KMemoryInfo: Platform identified : "LINUX" KMemoryInfo: TotalRam: 8304119808 digikam.general: Allowing a cache size of 200 MB /tmp/.mount_9UXxlv/AppRun: line 73: 4142 Segmentation fault digikam.wrapper $@ ```
With AppImage, use a console and run with "debug" argument to use GDB and get a backtrace with 'bt' GDB command when issue occurs.
the backtrace: ``` [New Thread 0x7fffe5de9700 (LWP 4759)] [Thread 0x7fffe5de9700 (LWP 4759) exited] [Thread 0x7fffe65ea700 (LWP 4755) exited] Thread 3 "Digikam::ScanCo" received signal SIGSEGV, Segmentation fault.
