Tor anonymizing network Compromised by French researchers

It is not clear to what degree the researchers "compromised" the tor network. To make matters worse the news story seems to have some translation issues. I am not arma or nickm but from a quick reading it does not seem like a real threat.

  "But there are also hidden nodes, the Tor Bridges, which
  are provided by the system that in some cases. Researchers
  have developed a script that, once again, to identify
  them. They found 181. "We now have a complete picture of
  the topography of Tor," said Eric Filiol."

The researchers found 181 of over one thousand bridges[1]? That hardly seems like a complete topography of the network. In order to get bridges all you need to do is submit a https request to https://bridges.torproject.org or send an email to bridges@torproject.org from a gmail address. So they scripted https gets and SMTP? The bridge distribution system is designed in such a way that an attacker can not easily flood the system with requests and learn all of the bridge addresses. I imagine this is why they only learned 1/5th of the bridges.

The majority of the research seems to indicate that if an attacker can control 1/3 of the relays in the tor network he can influence its operation and decrypt/associate/identify traffic streams. The tor threat model has always stated that an attacker with control over a significant number of nodes could successfully compromise the security goals of the network. Furthermore the attack depends on users not utilizing trusted entry nodes. I do not think the attack would have any effect on a user who used a trusted entry node that the attacker did not control.
