Comment 9 for bug 369832

@teledyn The problem behind that Critical message has already been fixed in the upstream code, and it will be available in 0.6.95 release.

About the "Error while performing indexing", it could be caused because the tracker-indexer process crash, it is started again by trackerd, and it finds index file is corrupted. It means that:
1) tracker needs to handle the "corrupted index" situation correctly and
2) please report all crashes you can find in the tracker-indexer process to minimize the frequency of this problem.
