Making Mac's open/save dialog fast again

Out of nowhere I had to wait 20 to 40 seconds on my year old iMac before I could open or save a file. Some people reported that iDisk could be the problem, but I don't even have a mac-account! However, those reports gave me a hint.

Indeed, a ls /Volumes/ showed this:

MacintoshHD Wuala ._Ipod_van_Corine

There it is! My girlfriend's IPod was not in sight, and I dumped Wuala because it stops working after a hibernate. A simple

sudo rm /Volumes/Wuala sudo rm /Volumes/._Ipod_van_Corine

and all was well again.
