Unable to delete a file/folder I've got a pretty scary problem.
Yesterday I wanted to empty the trash but somewhere in the process it just hung up.
I rebooted a few times and tried it again and again but with no result.

I then used the terminal to delete the files out of the .Trash folder manually and I could narrow down the problem to one particular file/folder that I can't delete. If I try rm -rfv &lt;file/foldername&gt; it just hangs up. Even if I try to get more infos about the file/folder with ls -l it will hang up.

I also tried to repair the volume using disk utility with no success.
Tricky indeed, things to try


steps recommended by Apple (HT1526) but it seems you did most of them already
remove and recreate the whole trash folder: cd ~; rm -rf .Trash; mkdir .Trash; chmod 700 .Trash
delete by inode: cd .Trash; ls -i should give you the inode number; find . -inum INODE -exec rm {} \; deletes by inode number
hack rmi.c to compile under Mac OSX and use this to remove by inode directly (I haven't tested this)
boot into Recovery Mode (on Lion) or from DVD (Snow Leopard and earlier) and run fsck/volume repair
boot into single user mode (HT1492) and run fsck/volume repair
