Comment 2 for bug 30207

I am having the same problem with dapper today, the only difference is that konqueror accesses it via system:/media/fd0 rather than media:/fd0

Still it mounts the floppy, but never shows the contents, konquerors action icon swirls away like it's waiting for the contents to load. If I browse manually to /media/fd0 the contents are shown, and like you mtab and proc/mounts show the mount just fine. KDE just refuses to believe the disk is mounted, later clicks try to mount it again and fail with the message that it's already mounted.
