I'm running Lubuntu 13.04 and the MTP device in question is a Google/LG Nexus 4.
My computer is finding the phone with no problem and asks me what to do when I plug it in. I can browse the phone's storage and everything's there. However, if I drag files from it to my filesystem, the copied files and directories are all named with numbers instead of the names (I'm guessing these are the files' StorageIDs?), whereas the files are being rendered in Pcmanfm with their filenames.
Does anyone know of a way to get these files to copy to my filesystem with their filenames intact?
