I plugged a SD card into my laptop today and the KDE automounter went bonkers.
I found that if the device has a Label, then it gets mounted as /media/d());???}.
If it doesn’t have a label, then it gets mounted properly. Changing the label with dosfslabel to anything works, but mounts bad. So there seems to be a parsing error in the automounter, but only with FAT.
In desperation, I reformatted the card with JFS, just to get rid of this issue. (I don’t actually use the card for a camera. I just use it as extra storage on the laptop and I actually prefer an efficient FS with a small journal over the current trend with ext3/4.)
