I am running Elementary OS Luna which is based off of Ubuntu 12.04. Running the stock kernel. I am running LibreOffice 4.1 and OpenLP 2.0.2. Updated via official Ubuntu 12.04 PPA listed on the website.

When I try to import a presentation, none of the files show up in the open file dialog. I tried every file extention supported by LibreOffice (odp, pptx, etc). So I decided to try the drag-and-drop method. This showed the following error: Invalid File /home/wayne/testing.odp. Suffix not supported (see imaged attached below). Thinking that the extra period may be in the file name, not part of the error message I took a look at the files in the terminal. Everything seems to be fine. LibreOffice opens the files just fine.

I love OpenLP, and my intent is to replace our Windows machines with an opensource alternative. I've found Elementary OS Luna to be the most user friendly for our team. Plus it is a very efficient OS. If you need any further information, just let me know.

Thanks in advanced,
