From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040312 Description of problem: ethereal-0.10.2-1.1 and libpcap-0.8.3-2 from the current rawhide are incompatible, as libpcap-0.8.3-2 provides libpcap.so.0.8.3 but ethereal-0.10.2-1.1 requires libpcap.so.0.8.1. Probably ethereal should be rebuilt against the later version of libpcap.
*** Bug 120376 has been marked as a duplicate of this bug. ***
Fixed in latest build ethereal-0.10.3-1 which also includes several security fixes. Read ya, Phil
