USB sniffing / packet size

Hello there, newbie here, trying to use Wireshark to sniff / rever^H^H^H^H^H debug USB communication between a SONY digital camera and a PC running Kubuntu Linux 9.10. after initial headaches / freezes due to the nVidia chipset of my first PC, I successfully sniffed some USB packets (mouse) with Wireshark (binary installed from Ubuntu's repository) on an Intel chipset / Atom motherboard. I start wireshark from a Konsole window and run it as root (the only way I found to give it access to the interfaces). When I turn the camera on, Wireshark shows some communication, then it segfaults after eight warnings that the "file contains a record that's not valid". When rather than displaying on screen I try to save to file, the file is saved but I get an error message when I open it, saying that the capture file appears to be damaged or corrupt and a packet is 65584 bytes long, more than the maximum packet. I can see the data in the file though, just not the corrupt packets. Is this normal/expected? thanks for any pointers / help.
