Bug? LyX "crashes" when opening Embed. Objects manual

[Dave Hewitt]

With the User's Guide open and the TOC displayed, an attempt to open Help 
-> Embed. Objects crashes LyX. This does not happen when opening other 
manuals as the second one, nor when the TOC is not open. Watching the 
buffer, this seems to be related to the Dummy Docs opened with the EO 
manual. Can anyone confirm?

Win XP Pro, LyX 1.5.2
