Dissector sometimes not available - but all protocols are enabled

Hi everybody, I am using wireshark 1.2.0 to decode and analyse X.400 traffic on aeronautical message handling systems (AMHS). I am very happy for wiresharks support of the X411, X420 and P7 protocols. However, sometimes it decodes my captured TCP packets only up to the OSI presentation layer (pres) and ends up with telling me that the dissector is not available (see packet details below). The curiosity is - sometimes it does and sometimes not - although all protocols are enabled. Any ideas would be appreciated.
