Comment 36 for bug 1088260

Actually, This symptom happens not noly "Desktop" folder but also to "Downloads" when downloading files via Firefox.
In Korean , we have two folders for download files one for standard download folder by locale "다운로드", and "Downloads" created by Firefox.
Sometimes files are downloaded to the "Downloads" folder not to standard folder "다운로드"

That workaround worked for this case too,
XDG_DOWNLOAD_DIR="/home/bagjunggyu/다운로드"
