I have come across this issue also, I've seen people lose essays on Ubuntu this way and have to start them again. In fact, this is a very serious usability issue because:
1. It can result in data loss, including complete loss of important data, such as an entire essay.
2. Most users will fall into this trap, they don't notice the file is being saved in /tmp, they don't know that /tmp will be wiped when they restart their machine. I've seen experienced users loss documents because of this.

I suggest we raise the importance of this bug.
Also, see this blog post from Murray http:// www.murrayc. com/blog/ permalink/ 2006/10/ 31/tmp- does-not- belong- in-file- save-dialogs/ in which he recommends fixing the issue in GtkFileChooser:
"GtkFileChooser could warn about saving documents in /tmp, and/or not allow /tmp to be shown when saving documents."
