The powerpoint attached to https://support.atlassian.com/browse/CSP-29982 is causing an OutOfMemoryException because the open source library that we use to render PICT files is blowing up on one of the embedded PICT files.
PICT files are Macintosh metafiles that serialize Mac graphic function calls. Generally these get embedded when you copy and paste the image from the clipboard. A workaround would be to directly embed a different type of image by using Office instead of the clipboard.
