Having noted the various discussion regarding problems with wireshark I have tried everything to get it working , deleting all binaries, reinstalling MacPorts, compiling without X11 running, updating etc. nothing seems to work. I have found that if I run wireshark with the 'Automatic Scrolling in live capture' turned OFF it does not crash. However if I scroll down to the bottom of the Packet List pane whilst in capture mode wireshark crashes. Similarly if I have 'Automatic Scrolling in live capture' turned ON wireshark crashes when the pane fills up and it tries to draw information on the bottom line of the Packet List pane i.e as it tries to automatically scroll. This problem existed for me with the latest version of wireshark even under Tiger. sudo -b wireshark returns this in the terminal window when it crashes;- The program 'wireshark' received an X Window System error. This probably reflects a bug in the program. The error was 'BadMatch (invalid parameter attributes)'. (Details: serial 42521 error_code 8 request_code 152 minor_code 4) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)
