This is my sitemap: http://www.buddhaphoto.net/index.php?sitemap

How to fix this error ?

That's indeed a bug missed. Quick fix look at the zp-core/zp-extensions/sitemap-extended.php file around line 612 and wrap $imageobj->getDesc() like html_encode(strip_tags(imageobj->getDesc())). Then clear the sitemap cache to generate new ones.

Fix will be in tonight's nightly build as well.

Thanks for support
I tried but it still errors:

Try the nightly tomorrow, there is another part of hte google specific image sitemap that accidentally lacked escaping.

Thanks, i'm waiting for that

Any help for this error

Your site still runs 1.4.1.3. How about trying the current release or even the nightly build as suggested two weeks ago?

Sorry, i checked again, plugin is normal
