Hello,
Maybe I'm wrong, but it looks like the /etc/network/*.d/vlan conflicts
with normal behaviour of ifup/ifdown in wheezy.
The script ifup/ifdown already use "ip link" to configure and create vlan.
Configuration file /etc/network/interfaces
auto bond2.341
iface bond2.341 inet static
address 192.168.1.1
netmask 255.255.255.0
With VLAN package installed:
# ifconfig bond2.341
bond2.341: error fetching interface information: Device not found
# ifup bond2.341
Set name-type for VLAN subsystem. Should be visible in /proc/net/vlan/config
ERROR: trying to add VLAN #341 to IF -:bond2:- error: File exists

The scripts /etc/network/*.d/vlan should be modified or removed ?
On the web site of the author

<http://www.candelatech.com/%7Egreear/vlan.html> it's written : "802.1Q
VLAN code is now part of the official kernel, and has been for years and
years. MAC-VLAN code has been added since around 2.6.29. It is very
unlikely that you need to download anything from this site, the packages
are left here for posterity's sake."
Thanks.
