The mailing list for listmasters using Sympa

[Christian Dahlhausen <address@concealed>]

Hi, 
we are running Sympa 5.3.4 on ubuntu and discovered an issue if somebody wants to unsubscribe from a mailing list per -Unsubscribe- function from Gmail. The unsubscribe message that Gmail sends to Sympa  has something like "unsubscribe%20listname" as subject line. Looking furhter into this issue I saw that the headers (of an email sent to a list) don't look right. 


List-Subscribe: <mailto:address@concealed?subject=subscribe%20testgolive>
List-Unsubscribe: <mailto:address@concealed?subject=unsubscribe%20testgolive>



I don't know where to fix this issue, did anybody encounter a similar thing?

Thanks,
