Bug ID: 490634
Summary: When moving a file from ext4 to NTFS filesystem,
millions of lines of errors are flooded into the
systemd journal
Classification: Frameworks and Libraries
Product: frameworks-kcoreaddons
Version: 6.4.0
Platform: Arch Linux
OS: Linux

SUMMARY
When moving a file from ext4 to NTFS filesystem, millions (figuratively or
literally, depending on your operation speed) of lines of errors are flooded
into the systemd journal, at a rate of ~10000 lines/second. The NTFS system is
mounted with NTFS-3G. I haven't tested with other filesystems. It looks like
KCoreAddons is experiencing an infinite loop.
STEPS TO REPRODUCE
1. Make sure you have at least one ext4 filesystem and one NTFS filesystem on
your disk, and mount the latter with NTFS-3G through Dolphin.
2. Using Dolphin, create a file in the ext4 filesystem (e.g.
`/home/huanyu/test.txt`).
3. Select it and press Ctrl+X, so the file is cut.
4. Open a new tab and navigate to the NTFS filesystem (e.g.
`/run/media/huanyu/Data`).
5. Press Ctrl+V, so the file is pasted, and record the time of operation (e.g.
11:33:00).
6. Close Dolphin as quickly as possible, unless you want to see millions of
lines of errors literally.
7. Open a terminal and run `journalctl --since 11:33:00`.
OBSERVED RESULT
See the error messages below.
EXPECTED RESULT
This should not happen.
