You´re not alone.
Have had these crashes for about a year now.
They seem totally random, can happen at any location at any time (as far as I can tell). Never happened in WvW, but maybe that´s because Ive only spent an hour or so there.
The wierd thing is, sometimes it
1) crashes with GW2.exe has [..], and then I can restart the game fine and keep playing for hours.
2) crashes with GW2.exe has [..], and everytime a start the client again (ie get to character select or loading map) and the only solution is to restart the PC and/or repair client (restart is often much, much faster).
3) with GW2.exe has [..], and I can login again but everytime I open the map it crashes again (this havent happened the last month though, sneaky fix?)
As someone said it seems like the game somehow makes its own files corrupt at some point.
