found 1100201 1.2.4-1 thanks Hi. After a lot of tests (100 tries on machines with 1 CPU and 100 tries on machines with 2 CPUs), the issue seems completely fixed here in my setup. Thanks a lot!
I'm going to mark this as happening is bookworm, because, well, it happens in bookworm as well. If you have time and motivation, you might want to fix this in bookworm as well for a future point release. If not, the bug is already closed anyway, and it will remain that way. Thanks.
