I assume you're referring to the g_log calls?  There is a hidden 
preference in Wireshark's preferences file (see Help - About - Folders 
to see where the Personal Configuration is to find it under the filename 
preferences):

######## Console: logging level ########
# (debugging only, not in the Preferences dialog)
# A bitmask of glib log levels:
# G_LOG_LEVEL_ERROR    = 4
# G_LOG_LEVEL_CRITICAL = 8
# G_LOG_LEVEL_WARNING  = 16
# G_LOG_LEVEL_MESSAGE  = 32
# G_LOG_LEVEL_INFO     = 64
# G_LOG_LEVEL_DEBUG    = 128
console.log.level: 28

This enables the g_log functions to print to the console (not to a log 
file).  If you're on Windows, make sure to enable the console window in 
the Preferences (under the Edit menu).  You can see it is set to 28 by 
default; that is the sum of the values of G_LOG_LEVEL_ERROR, _CRITICAL 
and _WARNING.
