Comment 7 for bug 1638245

Sorry I'm just a user, I don't know much about these source codes, I thought it was a fix, but if it simply forces skipping the patch, it's no good for you, of course ;-)

To reproduce the problem you need another partition other than the one where the user home directory is, and follow these simple steps:

1) Go to Desktop.
2) Create a symbolic link to any folder in another partition (or disk) in your computer (i.e. not removable media)
3) Click that symlink on your desktop to access that folder.
4) Create a new document there - any type of file, even empty, will do.
5) Press the Delete key to move that file to trash: you should see that message telling you it can't be done (although you can safely move any subfolder or any file in subfolders to trash, and although you can do it if you access that folder directly instead of going via that symlink on your home partition).
