Steps to reproduce:
- Start Wireshark
- Open attached capture file
--> Frame No. 11 shows correctly as WriteResponse
- Close capture file (don't close Wireshark)
- Open attached capture file again
--> Frame No. 11 shows as (Message fragment 54) without being disassembled

When opening the capture file for the second time, the dissector seems to be in
a different state than on the first time, as the WriteResponse is not displayed
correctly.
