I am calling a web service, which (apparently) returns a *massive* amount of
data. HTTP response header indicates a content length of 17,779,043.

When attempting to reassemble the HTTP response, WireShark crashes.

This issue occurs in both 1.6.6 and 1.7.0.
In 1.6.6, I received an error that looked something like: dissector bug
protocol xml more than 1000000 items in the tree
in 1.7.0, I get a simple MFC error.

I have identified that the bug is not in the capture, but rather in the
reassembly... WireShark freezes not immediately when the call returns, but
rather a few seconds after... additionally, I used Network Monitor to capture
(which worked fine, but their UI blows, and I can't find a way to reassemble),
but loading the capture file into wireshark causes the same crash.

This appears in the windows event logs:
Faulting application name: wireshark.exe, version: 1.7.0.39768, time stamp:
0x4eb990e8
Faulting module name: libglib-2.0-0.dll, version: 2.26.1.0, time stamp:
0x4d1b271d
Exception code: 0x40000015
Fault offset: 0x000000000005180e
Faulting process id: 0x20d0
Faulting application start time: 0x01cd11b455b71bc0
Faulting application path: C:\Program Files\Wireshark\wireshark.exe
Faulting module path: C:\Program Files\Wireshark\libglib-2.0-0.dll
Report Id: 9c55379b-7da7-11e1-ba75-782bcb944eb3

I wish I could attach the capture file, but it does contain sensitive
information.
