From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I think the problem with xournal is that it cannot ask a file portal to give it access to two related files at once. "I want to let the user pick foo.pdf.xournal, and also give me access to foo.pdf". So the next best thing is to give it the "access any damned file" permission, and let Xournal grab whatever it wants. You get the same problem with video players - you could take away their permission to open-any-file, but then they won't be able to pick up a related subtitle file.
