I hope I am not missing something entirely with this bug, but I searched for similar issues and found nothing.
I have just encountered this issue today – 01/10/2013. On two separate characters running solo on two separate PVE maps, I tried to enter WvW via the top menu icon and the screen it pops up. The loading screen changed to the WvW screen and the loading icon in the bottom right corner spun for all of two seconds before stopping entirely. A few seconds after that, my game crashed with an error message which is shown in the attached file.
I was not guesting, nor was I in an overflow map, if that helps. I tried entering several different borderlands and got the exact same error. I have successfully entered WvW before, and there have been no changes to my GW2 installation or my PC hardware or settings.
Thanks!
—Edit—
Perhaps I should have posted this in the tech support forum instead. Apologies if that is the case, but I successfully entered WvW earlier today and, as I stated, there have been no changes to my hard or software since then.
