I've seen them in one official part, and one part on the tracker.  But since I
haven't really been looking for them, I'm guessing they exists in other parts.
The main culprit appears to be pre-existing parts that were later BFC-certified.
(Both parts I've seen this in fall into that category.)  The bow-ties weren't
removed during the BFC certification process.

I think bow-ties are much less common in parts initially created within the last
few years.  However, they're fairly common in old parts, and when someone goes
in and updates them for BFC, this problem can occur.

As for the tracker, either it doesn't detect this in an automated way, or the
admin insertion of an update for an official part doesn't go through the
automatic error detection process.  I assume it's the former, since the latter
would indicate a bigger problem.


Do you spit out any error messages?

I'll be generating errors in LDView 3 when this happens, and warnings when
bow-ties are detected in non-BFC-certified sections.  LDView 3 will generate
both errors and warnings; previous LDView versions only generated errors (some
of which were more accurately warnings, probably).

(On a side note, I don't expect LDView 3 to be publicly available for at least
two months, and it could be longer.  It's currently nearly feature-complete and
in the alpha test stage.)
