I can confirm this bug. In my case I have the VPN down through which most
accounts I access (Facebook, gtalk, icq). When empathy starts it immediately
eats up 100% CPU (telepathy-gabble) and continues to do so even if I set it to
offline.
An strace on the telepathy-gabble contains polls and empty receives only:
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}], 2, 0) = 0 (Timeout)
recvfrom(11, "", 6, 0, NULL, NULL) = 0
recvfrom(10, "", 6, 0, NULL, NULL) = 0
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}], 2, 0) = 0 (Timeout)
recvfrom(11, "", 6, 0, NULL, NULL) = 0
recvfrom(10, "", 6, 0, NULL, NULL) = 0
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}], 2, 0) = 0 (Timeout)
recvfrom(11, "", 6, 0, NULL, NULL) = 0
recvfrom(10, "", 6, 0, NULL, NULL) = 0
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}], 2, 0) = 0 (Timeout)
recvfrom(11, "", 6, 0, NULL, NULL) = 0
recvfrom(10, "", 6, 0, NULL, NULL) = 0
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}], 2, 0) = 0 (Timeout)
recvfrom(11, "", 6, 0, NULL, NULL) = 0
recvfrom(10, "", 6, 0, NULL, NULL) = 0
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}], 2, 0) = 0 (Timeout)
recvfrom(11, "", 6, 0, NULL, NULL) = 0
recvfrom(10, "", 6, 0, NULL, NULL) = 0
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}], 2, 0) = 0 (Timeout)
recvfrom(11, "", 6, 0, NULL, NULL) = 0
recvfrom(10, "", 6, 0, NULL, NULL) = 0
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}], 2, 0) = 0 (Timeout)
recvfrom(11, "", 6, 0, NULL, NULL) = 0
recvfrom(10, "", 6, 0, NULL, NULL) = 0
