 I use tor only as a client to connect icedove to the tor network with
 the extension Torbirdy (on port 9050). With the tor version 0.2.8.6 I
 can't immediately connect to any mail server or news feed after the pc
 woke up from standby ("long" time in standby) and I started icedove. I
 have to wait for several minutes in order to connect successfully, but
 the timespan seems to be random. This does not occur after a (re)boot.
 The first version I remember to have this issue is 0.2.8.6-2, I did an
 upgrade from 0.2.7.6-1 to 0.2.8.6-2, so I skipped the alpha and rc
 versions and the first upload to unstable. I am very sure that the issue
 didn't occur in version 0.2.7.6-1 which I used for several months. I can
 exclude network connectivity problems because e.g. I can immediately
 start the Tor Browser after standby.

 Today I purged tor, installed version 0.2.7.6-1, copied the old "state"
 file to /var/lib/tor, and set the pc in standby mode for a couple of
 minutes. After waking up from standby I immediately tried to connect to
 a mail server which worked. Then I upgraded step by step to every
 version of tor 0.2.8 which I could find on snapshot.debian.org and tried
 to connect to a mail server immediately after waking up from standby.
 Unfortunately I could not reproduce the bug then. Finally with version
 0.2.8.6-3 the bug occured again, but only after a "long" standby time
 (almost 90 minutes).

 Attached are two log files from the weekend and the complete log from
 today after the installation of version 0.2.7.6-1.

 As you can see, the bug is not easily reproducible, and the logs don't
 show any particular reason for why tor does not open new circuits
 immediately. Please tell me what I can do to give you more information
 about the bug.
