+Product: Mono: Debugger
+Version: 1.1
+OS Details: 
+Status: NEW   
+Priority: Normal
+Component: cli

+TargetMilestone: ---
+Summary: "file" command doesn't check to see if arg is valid file
+Open up the debugger, and at the (mdb) prompt, type an invalid path into
+the "file" command:
+(mdb) file /asdf/foo/bar.exe
+Executable file: /asdf/foo/bar.exe.
+If you then try to run, you get:
+(mdb) run
+Starting program:
+ERROR: Caught exception while executing command
+Mono.Debugger.Frontend.RunCommand: System.ArgumentException: An invalid
+argument was specified.
+Server stack trace:

+Along the same lines, if you pass an invalid path into mdb, you get no
+indication that it doesn't exist until you try to run.
+$ mdb /asdf/foo/bar.exe
+Mono Debugger
+(mdb) r
+Starting program: /asdf/foo/bar.exe
+ERROR: Cannot exec `/asdf/foo/bar.exe': No such file or directory
