Open-behind is only useful for small files when the workload is mostly open + read + close, and quick-read is also enabled (which is not your case). The only effect it will have is that the latency "saved" during open is "paid" on the next operation sent to the file, so the total overall latency should be the same. Additionally, VM workload doesn't open files frequently, so it shouldn't matter much in any case. That said, I'm not sure if the problem is the same in your case. Based on the stack of the crash, it seems an issue inside the disperse module. What OS are you using ? are you using official packages ? if so, which ones ? Is it possible to provide a backtrace from gdb ?
