Starting with this commit I can reproduce some weird behavior when changing workspaces. To reproduce:

1. Open a document from the Help menu (I've been testing with Beamer).
2. select text.
3. switch workspaces.
4. switch back.

Result: the text is gone.

Note that the buffer is read-only (since I opened it from the Help menu).

Note also that after the text disappears "undo" does nothing since it's disabled (since it's read only).

If I preview to PDF, then indeed the text is missing there also so it does appear the buffer was modified.

It seems that switching workspaces somehow send a signal that is not being processed correctly?

Here is a short screencast (warning: I accidentally enabled sound).

Can anyone else who uses switch workspace reproduce?
