PDF Export throws an exception when an unterminated macro is used in a heading

The PDF Export code can't handle the following wiki markup snippet. It just throws an exception. The markup may be invalid, but still the PDF renderer should cope with invalid input without throwing an unhandeled exception. Not good.

Wiki markup:

h1. {color:red}foo

bar

{color}

Exception:

com.atlassian.confluence.importexport.ImportExportException: org.apache.velocity.exception.MethodInvocationException: Invocation of method 'exportWikiToXslFo' in class com.atlassian.confluence.importexport.impl.WikiExporter threw exception class com.atlassian.confluence.renderer.WikiRenderException : Error while generating XSL-FO for '~admin:pdf test'
