This is a bug in Strigi ( the file analyzer ). If you can reproduce at will, can you contact with the Strigi developers and tell them your problem ? They will give you some steps to get a better trace to help fix the problem.

There is an already reported issue with large .tar.gz files at: http://sourceforge.net/tracker/?func=detail&aid=2645583&group_id=171000&atid=856302
Thanks

KFileMetaDataProvider: Don't crash if a Strigi analyzer crashes

Some Strigi analyzers are still unstable and crash under certain circumstances. This patch moves the reading of the meta-data into a custom process instead of doing it in a thread, which assures that a crashing Strigi analyzer does not result in crashing Dolphin or Konqueror when hovering some items.
