Hello,
I cannot undersand why I have a critical memory leak with digikam, conducting it to crash when RAMand SWAP are full. I've tried several downgrades, without significant results.
you can find below some outputs of$ valgrind --tool=memcheck --leak-check=full --error-limit=no digikam
Please, help me to understand.
