It appears that a recent software update has broken some, if not all, generator queries.

http://en.wikipedia.org/w/api.php?action=query&generator=allpages&gaplimit=3&gapfrom=Ba&prop=links|categories returns this:

<?xml version="1.0" encoding="utf-8"?>
<api>
  <error code="internal_api_error_MWException" info="Exception Caught: Database::makeList: empty input">

Also, http://en.wikipedia.org/w/api.php?action=query&generator=backlinks&gbllimit=5&prop=info&gbltitle=America&gblnamespace=0 gives a very similar error dump:

<?xml version="1.0" encoding="utf-8"?>
<api>
  <error code="internal_api_error_MWException" info="Exception Caught: Database::makeList: empty input">

#10 /usr/local/apache/common-local/live-1.5/api.php(3): require('/usr/local/apac...')
#11 {main}

</error>
</api>

However, http://en.wikipedia.org/w/api.php?action=query&generator=backlinks&gbllimit=5&prop=info&gbltitle=America (without the gblnamepsace=0 parameter) still works, and some other generators also work.
