It seems I am not that original. When I went on the Konqueror bugzilla
report what had occured, I saw that several similar bugs (crashing on
mir.aculous (sp?) site, etc. had already been posted, and, more
that the bug has been resolved in the current development release.
So, next release needs to be checked out again, for this great little
browser / file system explorer / multi-protocol file-sharer.
