Did you try to reproduce the issue with a fresh profile?

I just did on your suggestion.  The bug does not occur under default settings, but if you set the preference browser.showQuitWarning to true then the bug will occur on a fresh profile.

STR:

1) Create a new profile
2) Set about:config > browser.showQuitWarning = true
3) Open several tabs
4) Open a New Private Window
5) Close the Private Window

Anyway, I'm not sure if it's a valid bug, because the private window inherits the settings from its parent window. Of course, this pref doesn't have any sense for a private window.
