Severity: normal
File: /usr/bin/slirpvde

After creating a VDE switch with

  % vde_switch -s . -m 660 -p vde_switch.pid -M vde_switch.mgmt --mgmtmode 660 -g madduck

I get

  % ls
  vde_switch.mgmt    ctl    vde_switch.pid

I then start slirpvde:

  % slirpvde -sock ctl -dhcp -D 
  IP address of your DNS(s): 192.168.2.1
  zsh: segmentation fault  slirpvde -sock ctl -dhcp -D

This issue is related to #484265: libvdeplug (used by both slirpvde and
vde_plug) and vde_switch didn't convert the socket pathnames to absolute
ones, so when they exchanged information about them there was no
agreement if the CWD differed. In addition, slirpvde didn't check for a
successfull connection to the switch.

I believe I have fixed them in the VDE SVN, we'll soon make a new VDE
upstream and Debian release.

Thanks,
Ludovico
