[Plugin: IntenseDebate XML Importer (Blogger to WordPress)] Import Stalls

This plugin stalls partway through the import process. No error messages, no nothing. Just stops maybe 40 posts in. Doesn’t matter if I choose Exact title match or Intelligent, regular or simulation mode, reimport any number of times, it always stops in the same place.

Is there any way to resolve this? Or are these comments lost for good?
