Description

When printing any document with at least 18 pages to the Guacamole printer, the resulting PDF ends up corrupted (Ghostscript crashes), and the RDP session is disconnected in the next window resize event.

1. Open a document with at least 18 pages, i.e. https://docs.oracle.com/javase/7/docs/api/index-files/index-1.html
2. Print the whole document with the Guacamole printer and try to open the resulting PDF file. It'll be corrupt.
3. Go back to the Guacamole RDP tab on the browser and resize the window to trigger the reconnect. The RDP session will be disconnected.
