Comment 6 for bug 30842

Guess not, according to the KDE bug report it's been fixed for a while. But sounds like the same problem:

I was running low on disk space, so I was cleaning up some files. I already did that about a week ago, but it turned out I freed up very little space. Turned out several folders were still in ~/.local/Trash/file, I had to run sudo rm -rf to delete them. Without sudo, they wouldn't get deleted so I guess for some reason I wasn't the owner. I am pretty sure I didn't get any error messages when trashing them in the first place or emptying the trash.
