Usually when this sort of thing happens, you have to drop down to the Unix level to go in and manually delete the file.
I forget the exact path to the Trash folder off the top of my head, and my MBP is packed away at the moment, so I'll defer to someone else on the specifics. But if you already know the basics of navigating the filesystem via Unix commands and how to delete files, then you should already have enough info to do it yourself.
I have an iMac with 10.5.8.
I have a strange and unknown file in the trash that will not go away. It has a horizontally broken name that looks like "nnnnE", has zero kb and a date of December 31st, 1903. When I empty the trash is stays there. If I try to get info on it, the info box pops up and then immediately disappears and the file disappears from the trash but will reappear as soon as I click on the trash. It's been in the trash for weeks now. I've tried everything I can think of. I've repaired permissions, I've run antivirus software. I've downloaded apps to force empty the trash--didn't work. I've used Disk Warrior to rebuild the directory. I'd post a photo of the file in the trash but this site doesn't seem to allow that. Does anyone have any suggestions or know what this is.
