[sylpheed:32810] Application bug, race in MSG_PEEK.

Hey *,

since some time (either since 2.6.0 or since kernel 2.6.28, didnt have
time to test that), I get the following message in dmesg:
TCP(sylpheed:<PID>): Application bug, race in MSG_PEEK.

That happens several times, but I did not find any situation to
reproduce it easily.

Does someona has an idea what that could be?

regards
Evgeni
