Skype (a popular VoIP and IM application) uses a proprietary (and encrypted) protocol. So far Wireshark is not able to decode Skype traffic because no one has been able to reverse-engineer the protocol. Each of these protocols fills a niche, providing well-tuned functionality for specific purposes or application domains. First off, Wireshark doesn't have explicit Skype support yet so you won't get pretty decodes. that some protocols are not decoded properly by Wireshark, which made me sad. Engineering design is about making the right set of trade-offs, and these trade-offs must balance conflicting requirements such as generality, ease of use, richness of features, performance, memory size and usage, scalability, determinism, and robustness. I can't find a working address of the author to ask him whether he would be willing to relicense his code to GPLv2+. In the packet detail, toggles the selected tree item.
