To security? Uh... sorry, then. Still, I can't see how I have done it. I 
have only gentoo-hardened in the destination of my local copy of the post, 
neither I found it in the MARC archive of gentoo-security (but maybe it's 
lagging behind).

...of course. And I was unprecise, I meant segfaulting, not core-dumping, of 
course. Sorry, I'm a bit tired here :). Anyway there is both a sigsegv in 
the app and an oops (a NULL pointer dereference while unregistering the vlan 
device) in the logs. _And_, I reproduced the segfault, I mistakenly forgot 
that I'm in permissive mode :), so the vconfig requires access to the /sys 
(and, when provided with it, it works). It shouldn't segfault, but that's an 
app's bug probably.
