AppKit is pretty good at logging failures like this. I would look for messages in the system.logs (or better yet from a sysdiagnose archive) from your process as well as com.apple.appkit.xpc.openAndSavePanelService (the process that actually shows the open/save panel). See if there are any logs around the time of the failure that could shed some light on what happened. Good luck.
