Version:           1.2.80 (using 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2)) "release 138", KDE:KDE4:Factory:Desktop / openSUSE_11.1)
Compiler:          gcc
OS:                Linux (i686) release 2.6.27.23-0.1-default

I select files in one directory and then copy it (CTRL+C or RMB->Copy) and the I paste it to another directory (CTRL+V or RMB->Paste).

The problem is that some files get renamed in the destination directory, for example:
- original name: "some.file"
- new name: "file:⁄⁄⁄path⁄to⁄destination⁄directory⁄some.file"

This problem occurs only on some files, but if I delete these files and repeat the process the same files will be copied with the prepended full path in their name - it doesn't appear to be random.
