--- Comment #37 from Daniel Lynn daniel.eric.lynn@gmail.com --- Since the release of the expansion pack (Heart of Thorns), these crashes have become more frequent. Not just using wine, but for native Windows users as well. The developers have formally addressed this as a known issue:

So, while it may occur more frequently on wine, it looks like ArenaNet needs to fix the core cause of this issue before we have a shot at figuring out why it is more frequent on wine.
I propose that this bug be marked as NOFIX since the true issue appears to lie upstream with the game itself. If they fix it and the game still has problems under wine, we might need to take a fresh look.
