One thing is to make sure that it is the first select-window which is failing:
there is a second one in there as well. Toggling debug-on-error and getting
a full backtrace (assuming you are loading .el files and not .elc files) would
take care of that.
If there were any concurrency, I'd suspect a race: you try to select a window
that somebody else killed in the meantime. But I don't think there is anything
like that going in emacs - but I don't know for sure.
