I've seen this as well in 10306 on Linux. You can switch to the old debugger to avoid hitting the problem (but you are just avoiding the problem). The problem is with RemoteString and multiByte file and I thought that that problem had been solved ... perhaps not for all cases?
If this is a problem for a number of folks, I could see if I can work out a workaround in the OTDebugger until the underlying problem is fixed.
