SUMMARY I have tried to open one of the save backup files created by Krita, with the ".kra.1~" extension, only to be told Krita can't open it because it's not the right file type. After being renamed to ".kra" it opened without a problem. Krita, especially on Linux, should use file headers instead of extensions to determine if something is of a supported file type. This used to work previously. STEPS TO REPRODUCE 1. Change a valid .kra file's extension to something invalid. 2. Try to open it. OBSERVED RESULT Krita will claim it's the wrong file type. EXPECTED RESULT Krita should open the file like it used to. SOFTWARE/OS VERSIONS Krita Version: 5.0.2 Languages: en_US, en, en_US, en, hu_HU, hu Hidpi: false Qt Version (compiled): 5.15.2 Version (loaded): 5.15.3 OS Information Build ABI: x86_64-little_endian-lp64 Build CPU: x86_64 CPU: x86_64 Kernel Type: linux Kernel Version: 5.17.1-arch1-1 Pretty Productname: Arch Linux Product Type: arch Product Version: unknown Desktop: KDE OpenGL Info Vendor: "NVIDIA Corporation" Renderer: "NVIDIA GeForce GTX 750 Ti/PCIe/SSE2" Version: "4.6.0 NVIDIA 510.60.02" Shading language: "4.60 NVIDIA"
The problem is with the shared-mime-info database which doesn't recognize all Krita files anymore because of a change in zip library. I've actually sent a patch upstream already.
