Sometimes HTML exporting fails and redirects to xwiki/pages/xwiki/Main/Search.html

I've created a Test space under Main, to result

http://localhost:8080/xwiki/bin/view/Main/Test/

Than try to export the Main page. Sometimes it let's you export it, so try several times. I couldn't find exactly how to reproduce it, but you will get main-search.png

http://localhost:8080/xwiki/pages/xwiki/Main/Search.html

I reproduced it over 4 times.

Reproduction steps:

• Open the main wiki page: http://localhost:8080/xwiki/bin/view/Main/
• Go to "more menu" -> "Export" -> "Other formats"
• Open the tree, click on select "none" to uncheck all and check "Solr Search"
• Click on "Export as HTML"
