Emptying the trash failed with "can't copy" on Yosemite

While using empty stack securely under Yosemite, it halted with the message:

You can't copy the item InfoPlist.strings because its name is too long or includes characters that are invalid on the destination volume.

What's the matter and, more important, what can I do about it?

PS. It might be that the InfoPlist.strings is located on an MS-DOS (FAT32) partition on an USB disk. (On which I lost 130 GB because I deleted that data.)
