Control: tag -1 + moreinfo Ok. This one, just like the other bug of this theme (#999421), seems to be fixed in current qemu (7.1) in bookworm. At least I can't reproduce it anymore, and our reproducer (lyx install) succeeds now.
Andreas, can you verify it is fixed for you? From the previous info, it looks like some wrong syscall emulation has been fixed since. Thanks, /mjt
