Version: 1.4.1 (using KDE KDE 3.5.7) Installed from: Debian testing/unstable Packages OS: Linux "When deleting many pictures at once by hitting the delete key quickly and repeatedly, Gwenview will try to delete the same file twice. The error reads: 'The file or folder .../cassiariley4danni 00.jpg does not exist.'" This is Debian bug #416451. The files are only 100k-200k.
This report is against a quite old version(KDE3), and I do not have such problem when using KDE SC 4.8 beta2. Feel free to reopen if it still happens in recent version .
