When I open KFind (in KDE 3.5) and search in 'file://' for any file name (with
no additional options, such as file contents) with 'use search index' enabled,
then press the 'Stop' button after a short time, it closes and the KDE segfault
dialog appears.  I have been able to consistently reproduce this problem, with
the exact same results each time.  Is there any more information that's needed?
 Here's the stack trace:
