BUG/MEDIUM: session: NULL dereference possible when accessing the listener
When implementing a client applet, a NULL dereference was encountered on
the error path which increment the counters.
Indeed, the counters incremented are the one in the listener which does
not exist in the case of client applets, so in sess->listener->counters,
listener is NULL.
This patch fixes the access to the listener structure when accessing
from a sesssion, most of the access are the counters in error paths.
Must be backported as far as 1.8.
