I'm not seeing that error, but I am seeing a warning that might be
related:

[00007f7ff7b5b678] qt4 interface error: Unable to load extensions module

I remember this also appearing with previous versions
(multimedia/vlc21) and since the program runs and plays fine and
doesn't crash (for me), I hadn't taken the time to look into it.

Aside from the clang hypothesis that you mention, other possible
differences between my setup and yours are:
1- I'm running NetBSD/amd64 7.99.5
2- The package that I've run-tested was built without dbus (I
compile-tested all options, but so far I've only test-run the version
that I would normally install).  Come to think of it, the dbus option
in vlc21 was commented out in options.mk with the remark XXX Broken,
though I haven't yet figured out why.

I'll try to test the package built with default options on my machine,
but I probably won't have time to look at this much this weekend.  I
hope to be able to come back to the problem next week.  Any chance of
building vlc with debugging symbols to get a more useful backtrace?

[I freely admit that debugging a multi-threaded app of this complexity
is way out of my depth, so any advice or assistance will be gratefully
received.]
