Attempting to email as PDF a Journal file - Reader reports error creating file sdcard/public/email_attachments/Sketch.pdf (could not open file) Device storage could be full. Same error if I try to save as PDF. It will save to my external SD card though.

It's not full

There are several images in my library, I assume samples, Attempting to open one crashes the image viewer.
The image viewer works fine on any of my images.
However, attempting to add an image to the library produces an error. It begins to load and switches to error while adding: file name.
Anyone else?
