I have categorized it as a crash. The "Build search index"-function reports that the search index was created, but if I press "Details" I get the error messages below. And if I choose the function again it tells that the index does not exist yet.
And when I use the search-button it gives strange results. For instance "text editor" gives no results but "editor" gives 5 results, one of them: 
"ed - text editor"
