I have a Lua plugin dissector which in some cases (for some packet in a file when it's opened, but not when clicked on the packet) apparently doesn't run to its end (observed through Lua console printout at entry and exit); it seems silently aborted at some point, I guess due to some error within. No error dialog box, no red packet details line and no Lua console message shows up when the error in the registered dissector code occurs. Isn't there any way to get informed about the place and cause of dissector script abortion?

I think there must be a better way, but the only one I've found (besides inserting prints here and there) is setting a debug line hook like

function hookl(event, line)
    print(event..' '..line..' '..tostring(debug.getinfo(2).name))
end
…
    debug.sethook(hookl, 'l')
…
    debug.sethook()

and seeing where the console output stops.
