When the meta description gets built from calling apply_filter("theme_head") quotes are not stripped out of the string. I tried this both with the theme I am using as well as the zenpage theme with the same results.
I a using Zenphoto version 1.4.2.1 [9180]
One the documentation page
http://www.zenphoto.org/news/zenphoto-plugin-architecture#Themeit says "before the <head>" instead of after.
Thanks

You nailed it acrylian thanks. I had forgotten that was where that was coming from.
I sorted this out by changing the way that the zpMinimal theme was building the description meta tag and not using the stuff from the plugin.
I was finding too much extra junk from my articles (pastes from email line endings in particular and extra spaces). Because of this the og:description for the fb like button was severely shortened. Getting the description meta tag cleaned up sorted out the problem and got nice long descriptions on fb.
If you made changes to the plugin though I'd be glad to test it.
I probably went a bit overkill with mine but it seems to work nicely now.
But this has nothing to do with zenphoto and is just friendly banter at this point. You can see the results from any of the news articles from my sowearedads.com/news.
