help understanding complicated client logs

I have a fairly large GWT application that works fine until it is behind SSL.  When that happens whenever the page is reloaded on about the 5th try (but it doesn't seem to have a pattern) I'll get an error that is something like:

    __gwt$exception: <skipped>: Cannot read property 'Z' of null

Since it is intermittent it is likely reloaded to the load order of resources.  My guess is SSL slows things down enough that in some cases something breaks.  But what?  So I made a detailed build to see if I could get more information.  What is produced doesn't make sense to me but hoping to someone it does.

I tried putting SSL on my workstation but I couldn't reproduce the problem.  My guess is things are too fast.  So, the only way I can reproduce is by contacting a remote server, where I don't have a development environment to debug.

Anything look interesting?  Any guidance is appreciated!
