tor 0.1.0.11 crash on Debian testing

[Jan Tore Morken]

Hi,
I had tor suddenly stop working for me last night, running tor 0.1.0.11 on Debian testing.

Checking /var/log/tor/log I found this:
[err] routerlist.c:242: mark_all_trusteddirservers_up: Assertion router->dir_port > 0 failed; aborting.

tor dies almost immediately after running it. A core dump is saved in /var/lib/tor.


# sudo -u debian-tor tor RunAsDaemon 0

Jul 15 13:21:41.568 [notice] Configuration file '/etc/tor/torrc' not present, using reasonable defaults.

Now, by renaming /var/lib/tor/cached-directory and running tor again to get a new version of it, the problem is solved.

A copy of the file not working and the core file is here: http://wobbled.org/tor/

Sorry, I'm a bit of a hurry when writing this, but if you have any further questions, feel free to ask.
