As you all are aware FAT32 and NTFS doesn't allow certain characters in filenames. Unfortunately in recent versions of Android Google decided to go with compatibility over what makes sense to "powerusers". There's a custom FUSE layer over EXT4 on Android, and recently a change was made to disallow extra characters in filenames, probably to make Windows users happy. So in short: 1. Try to copy a file over MTP to an Android 13 device. Say, filename contains ":" or "colon" if you will. 2. Copy job times out when encountering offending file. 3. After about 30 seconds I get a dialog asking to retry, but MTP breaks. 4. "Skip" option is not doing anything, it times out like on step 2, only "Cancel" option does its job. Browsing of MTP device is broken and it needs to be reconnected to recover. Can we fail without breaking connection? Ideally KIO would detect what the problem is and propose a filename change. 21/07/2023 16:40 kernel usb 6-2: new SuperSpeed USB device number 9 using xhci_hcd 21/07/2023 16:40 kernel usb 6-2: New USB device found, idVendor=18d1, idProduct=4ee1, bcdDevice= 4.40 21/07/2023 16:40 kernel usb 6-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 21/07/2023 16:40 kernel usb 6-2: Product: Pixel 4a 21/07/2023 16:40 kernel usb 6-2: Manufacturer: Google 21/07/2023 16:40 kernel usb 6-2: SerialNumber: Redacted 21/07/2023 16:40 dolphin 16:40:04.878 INFO DeviceManager:449 Device added: "mtp://Google_Pixel_4a_12021JEC201128/" QList("mtp://Google_Pixel_4a_12021JEC201128/") Snippet from logs: 21/07/2023 16:41 org.kde.kmtpd5 Error 2: PTP Layer error 02ff: LIBMTP_Send_File_From_File_Descriptor(): Could not send object. 21/07/2023 16:41 org.kde.kmtpd5 Error 2: Error 02ff: PTP I/O Error It's part a bug report because of MTP connection breaking, and a wishlist item for filename correction logic.
