--- Comment #3 from Simon Westersund <simon.westers...@iki.fi> --- I tested again with GDB enabled and now the face scan crashed with a segmentation fault, after it printed the warning that was added. The backtrace was as follows: [New Thread 0x7fff390e8640 (LWP 92762)] digikam.general: SharedLoadingTask not found!!! --Type <RET> for more, q to quit, c to continue without paging-- Thread 70 "Thread (pooled)" received signal SIGSEGV, Segmentation fault.
