--- Comment #6 from Enrico Ronconi <[email protected]> --- (In reply to Akseli Lahtinen from comment #4) > One more question, what filetypes are they? In my case, I've found that the problematic file is a ".3mf" (3D manufacturing) file that I had on Desktop (that's explains why I had problem "on boot"). Dolphin shows others 3mf files correctly, so I think there is something wrong with this specific one. 3mf is indeed a ZIP file with some metadata, 3D model, and a PNG preview "thumbnail.png". I'm pretty sure Dolphin shows this thumbnail.png as the actual preview. This also would explain why the preview is shown despite only "GIF/PNG" preview is ticked in Dolphin. However, If I extract this thumbnail.png, Dolphin has no problem with its preview. I've now attached the file in the report. I'VE DOWNLOADED THE 3MF FILE FROM INTERNET, so I can not guarantee it does not contain some 0-day exploit from NSA, but seems fine to me. -- You are receiving this mail because: You are watching all bug changes.
