That seems to prove that it's simply a mount problem.

Probably you only get that message when it needs a whole disk, like burning an

Not sure what you mean there, but maybe it's relelvant that any files in your 
wastebin are still actually there in your home directory?  I've never seen 
anything that makes me suspect a problem with this - never seen files that I 
believed to be deleted.

You need to know if anyone else has seen this problem, before reporting it.
