Title:
  python2.7 crashed with SIGSEGV in zorba::GlobalEnvironment::getStore()

Status in “python2.7” package in Ubuntu:
  New

Bug description:
  I experienced a segmentation fault when running the following report,
  whether or not the files have been previously tidied to well-formed
  xhtml by w3c's tidy utility. If I substitute the doc() function for
  html:parse() then the query proceeds as expected and produces results
  with no segmentation fault  ...

  >>>>>>>>>>>

  import module namespace file = "http://expath.org/ns/file";
  import module namespace html = "http://www.zorba-xquery.com/modules/converters/html";

  declare variable $origpath := "../notes/";

  <html xmlns="http://www.w3.org/1999/xhtml">
  	<body>
  		{
  		for $origfile in file:list($origpath) where matches($origfile,'.+\.html')  
  		let $absfile := file:resolve-path(concat($origpath,$origfile))
  		return 
  			html:parse($absfile)//h1
  		}
  	</body>
