I did the following steps, and then wireshark crashed:

1) Open a capture file in wireshark (sample file is attached in the bug report:
sample_bug.pcap)
2) Disbled All protocols from the menu->Apply->ok
3) Enabled All protocols from the menu ->Apply->ok
4) Wireshark-1.0 crashes at this point, and shows the follwing error:

Err  file packet.c: line 336 (dissect_packet): should not be reached

Backtrace is shown below:

Program received signal SIGABRT, Aborted.
