Wireshark has a method of showing debug messages on the console beyond  
what is displayed by default.  See ~/.wireshark/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

However, this will probably not display useful information since  
Wireshark is crashing in the middle of something.  The way to  
troubleshoot this type of problem is to use core dumps and a debugger  
such as gdb.  See http://wiki.wireshark.org/Development/Tips for more  
details and the link to gdb help.  Linux may be like MacOS X, which  
defaults to disabling core dumps, so you have to enable them first or  
run Wireshark through gdb.
