Package: shared-mime-info?? (update-mime-database) Version: 0.15-1 Severity: normal
I had the same problem: nautilus did not shown the JPG (uppercase file names) thumbnails and it reported the strange "security risk" warning after clicking on them. After some hacking, I found that the problem is solved by removing the HOME/.local directory. Later I have associated another application to JPEG files and still works fine. In this mail I attach my .local directory which caused the problem. I don't know the origin of the problem, but I suspect on update-mime-database, since the file ~/.local/share/mime/application/x-extension-JPG.xml doesn't have the "glob" tag (I'm not sure about if it is required; if added by hand and restarting gnome, it still fails). This is my second debian install (sarge); both done on the past 30 days, and I never was able to properly display JPG files at my first try (always performed a lot of time after installing, upgrading and tuning the important things). However if I create a new account from the Users and Groups tool, it works fine (no .local directory initially setup). Yours, Ciriaco.
