I'm not sure if the following is LyX's problem or not. If I open LyX
from the terminal (on Ubuntu 12.04) and copy the User Guide and exit,
the LyX window closes but LyX still hasn't exited (the terminal is
still busy). After about 5 seconds I get the following message on the
terminal "QClipboard: Unable to receive an event from the clipboard manager in
a reasonable time" and then LyX exits.

Now if I start LyX again and exit (without doing anything) I again get
the pause and the QClipboard message. The only way I can get rid of
this is to restart the computer or running the following command:
killall gnome-settings-daemon

Note that the copy also issued this message to the terminal:
Warning: latex had problems compiling 0lyxpreview.tex

This is due to LyX's trying to export various math things as images when doing the copy. We need to stop it from trying to do that.
