Created an attachment (id=7073)
 --> (https://bugs.wireshark.org/bugzilla/attachment.cgi?id=7073)
Frame 15 from the original fuzz'd file causes a crash.

The attached file fuzz-2011-09-21-28149-crash-frame.pcap contains 1 (libpcap
format) frame and will fairly consistently cause a crash when read 
via 'tshark -nVxr ...'

The crash appears to be somehow caused by the rdp dissector messing up memory.

When the crash occurs the actual crash in tshark happens when epan_init() is
called upon just before program-exit to free up memory (and not when executing
the dissection code).

If the rdp dissector is disabled, then the crash does not occur.

valgrind doesn't report anything interesting.
