Thanks for that information. Could you try rebuilding, like before, except go into the existing source directory (called "desktop-file-utils-0.10"), and run patch -p1 < desktop-file-utils.patch (where desktop-file-utils.patch is the attachment I added to this bug).
Then run sudo dpkg-buildpackage -uc -us This may fix the crash, but I'd like it to be tested, to be sure. ** Attachment added: "Patch to fix reading/writing invalid memory" http://librarian.launchpad.net/2552718/desktop-file-utils.patch -- desktop-file-utils -q always segfaults https://launchpad.net/bugs/43977 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
