I tried the program and was ethereal seemed to handle everything fine,
no crashes. Which version are you running?
Can you run ethereal like this:
ethereal -k -i eth0 -w /path/to/a/capture/file.cap
And get it to crash, if you can, send the capture file. (gzipped) Now,
are you sure ethereal isn't just crashing because it's running out of
memory? Those isic/tcpsic/etc. programs seem to generate packets at a
phenomenal rate, which will likely cause ethereals memory usage to shoot
through the roof very quickly. I've got a couple hundred meg of swap
configured and 128mb of real memory to protect against stuff like that.
