--- Comment #7 from Nikolay Sivov bunglehead@gmail.com --- (In reply to mgruber from comment #6)
I was in contact with Martin Přikryl (author of WinSCP). After several debug builds he was able to confirm that it's not a WinSCP bug: it's a bug in the Wine component which caches the icons and timestamps.
Any idea which component is this?
