Comment 198 for bug 441835

There is no obvious solution for fixing the permissions problem which is robust, nonintrusive, and architecturally sound. It at least requires right-click and "detect media...", before mounting, plus it requires unblacklisting floppies in /lib/udev/rules.d/95-devkit-disks.rules. This should be a slightly more comfortable workaround than having to resort to the command line, though.

Therefore retitling back to original problem.
