Description Bob Chiodini 2005-05-02 11:07:42 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050416 Fedora/1.0.3-1.3.1 Firefox/1.0.3

Description of problem:
Clicking on the start capture button, then checking "Update list of packets in real time", "Automatic Scrolling in live capture" and "Hide capture info dialog" under Display Options, then clicking OK results in a segfault.  

Version-Release number of selected component (if applicable):
ethereal-0.10.10-1.FC3.1, ethereal-gnome-0.10.10-1.FC3.1

How reproducible:
Always

Steps to Reproduce:
1.Clicking on the start capture button
2.Check "Update list of packets in real time", "Automatic Scrolling in live capture" and "Hide capture info dialog" under Display Options
3.Click OK
  

Actual Results:  Segmentation Fault

Expected Results:  Ethereal should display a live capture of the ehternet traffic.

Additional info:

Ethereal works correctly if "live capture" is not enabled.  strace output available, but very large +700K.  I can attach it (or some portion) if requested

Comment 1 Radek Vokál 2005-05-02 11:25:22 UTC

Please try with latest rawhide version.

> Please try with latest rawhide version. 

There were too many dependency issues, yum seemed to get caught in a loop trying
to resolve them.  Tried a nodeps install and had different problems, missing
libs.  Note this is the x86_64 version.  INstalled the i386 version it works.

Comment 3 Bob Chiodini 2005-05-02 21:23:01 UTC

Reloaded the x86_64 version and the debuginfo (possibly not the same rev)
available on the download server at redhat.com.  This is all new to me, but
here's the output (maybe of some help):

Comment 4 Radek Vokál 2005-05-03 05:59:59 UTC

I've tested this on x86_64 machine and it works with the latest version from
rawhide. Anyway, there'll be ethereal update in FC3 which will fix this issue
soon, so don't worry about yum dependencies (even though yum should also work
with rawhide).
