Please Install the Updated Packages.
The previous update of wireshark had the dumpcap program, which is required by both wireshark and tshark, in the wireshark package. If a user installed tshark, it would not properly operate unless the wireshark package was also installed. This update corrects the problem by providing a new dumpcap package that both wireshark and tshark require.
wireshark on Mandriva Linux 2008.0, Mandriva Linux 2008.0/X86_64
