There's some bug in this version of the tor client that drives me nuts, even when I'm connected to my network at some point I get:

[notice] Tor has not observed any network activity for the past 80 seconds. Disabling circuit build timeout recording.</p>
<p>[warn] Failed to find node for hop #1 of our path. Discarding this circuit.<br />

And then I have to restart the browser so that Tor bootstraps again and starts working again. This happened with Tor 0.3.2.1 but it intensified a lot with the recent version (I'm using Tor with bridges FWIW) Hope this bug gets higher priority.
