This is rather bizarre. The problem is revision 43646. I have
double-checked by reverting just those two lines on my local latest
trunk, and the bisection is accurate - somehow revision 43646 is the
problem.
I see that the code it calls does some things with the packet display,
but the crash is happening even on the main page before loading a
capture, so I'm at a bit of a loss. Any ideas?
