No, it also happens if you use "tethereal -V", and probably always happens if you run Ethereal. The problem was that there was a bug in the GTP dissector - it was using an 8-bit offset relative to the beginning of an area in the packet, and comparing it against an 8-bit length to see whether it was finished processing the area, but if the length is 255, that won't work, as an 8-bit offset can *never* be bigger than 255. Converting the offset to a "guint" made the problem go away. The packet isn't a GTP packet, apparently, but it was either to or from the right port numbers, so.... I've checked in a fix.
