Wireshark · Ethereal-dev: [Ethereal-dev] crash in Ethereal in printing from Follow TCP Stream if data displayed in HEX.

[Richard Sharpe <rsharpe@xxxxxxxxxxxxxxxxx>]

Hi,

With the current CVS, or pretty close, if you take say the telnet-raw.pcap 
capture from www.ethereal.com/sample/ and select Analyze-->Follow TCP 
Stream and then select Hex Data and click on Print, you get a crash.

The stack looks like this:

I don't have time to look at this problem right now, but might later.
