+Summary: Running HelloWorld fails with "Cannot read DWARF frame info from symbol file"
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+
+
+When I try to run a simple "Hello World" program from mdb it fails with
+"Cannot read DWARF frame info from symbol file
+`/home/build/mono-svn-install/lib/mono-debugger-mini-wrapper':
+System.ArgumentNullException: Argument cannot be null.
+Parameter name: src".
+
+Here's the detailed stack trace along with the command I used to compile:
+
+[build@server HelloWorld]$ mcs -g -o HelloWorld.exe *.cs
+[build@server HelloWorld]$ mono HelloWorld.exe
+Hello World!
+[build@server HelloWorld]$ mdb HelloWorld.exe
+Mono Debugger

+
+Steps to reproduce the problem:
+1. Compile a simple HelloWorld program using mcs -g.
+2. mdb HelloWorld.exe 
+3. type "run"
+
+Actual Results:
+
+See above.
+
+Expected Results:
+
+Should print "Hello World!".
+
+
+
+How often does this happen? 
+
+Everytime.
+
+Additional Information:
+
+This occurs with the mono/mcs and the debugger built from the latest SVN
+sources and with mono/mcs 1.1.6.  If there is a particular SVN revision
+which is known to work, please let me know.
