In LibreOffice Version 4.0.4.2 (Build ID: 9e9821abd0ffdbc09cd8c52eaa574fa09eb08f2) for Macintosh, I cannot open multiple files in the Finder (or from Path Finder). If I select 2 or more “.ods” documents and either double click or choose cmd-O, I get a message “[filenames] does not exist”. I can, of course, open the files one at a time.
I can supply further details, but this seems like a simple bug that many other people should have run into. I can’t imagine that there is something particular about my setup that causes this, but if others cannot replicate it, I can experiment.
I haven’t reported this as a bug, thinking that this forum is the first place to go.
