I'll try to reproduce this using a debug build of Latte Dock and also qt, since the stack trace seems to originate in the qt code. I'll report back next week when I got time.
I compiled latte-dock and qt with debug info and I've been running latte-dock under gdb for about a week now without any crash, while previously the crash can happen multiple times a day. I think it's safe to assume the latest git version somehow fixed this.
