Comment 2 for bug 882001

Confirming your own bug? Hmmm.

Anyways, I dont' have 11.10 to try this out on and I left the 12.04 box at home, but in 12.10 there is no issue with this. In fact, it recognizes there is a file of the same name and asks if you want to overwrite, rename, etc. Handles it quite well. This is with:

$ apt-cache policy pcmanfm
pcmanfm:
  Installed: 1.0.1+bzr801+201210081425~quantal1
  Candidate: 1.0.1+bzr801+201210081425~quantal1
  Version table:
 *** 1.0.1+bzr801+201210081425~quantal1 0
        500 http://ppa.launchpad.net/lubuntu-dev/lubuntu-daily/ubuntu/ quantal/main i386 Packages

     1.0.1-0ubuntu1~ppa1 0
        500 http://ppa.launchpad.net/lubuntu-dev/staging/ubuntu/ quantal/main i386 Packages

which is obviously a bleeding edge version (it's from lubuntu-daily as you can see) but it does indeed have a fix committed.
