+qemu-system-x86_64 prints obscure error message and exits when encountering an empty argument
+
+QEMU emulator version 4.2.1 (qemu-4.2.1-1.fc32) on Fedora 32.
+
+When writing a script to start qemu automatically, I ran into a very confusing error message due to a bug in my script and had trouble understanding it. I isolated the problem to the following:
+
+$ qemu-system-x86_64 ""
+qemu-system-x86_64: Initialization of device ide-hd failed: Device needs media, but drive is empty
+
+As you can see, running qemu with an empty argument prints a seemingly random and unrelated error message about an ide-hd device, and the program immediately exits with code 1. This happens when an empty argument appears anywhere in the arguments list, always causing the program to immediately die with this error.
+
+This is a simply baffling message to be encountering when the problem is really an empty argument.
+
+Expected behaviour: Either flatly ignore the empty argument, or at most trigger a warning (eg, "warning: saw empty argument"). It should not at all prevent the program from running.
