Please fill in this template when reporting a bug, unless you know what you
are doing.
Description of Problem:
When I try to debug any program (helloworld in this case) it will throw
error about not able to read the symbol files (of 64bit?!? I have x86)

I used mono-debugger 0.12 with Mono 1.1.13.4

Steps to reproduce the problem:
1. mdb test.exe
2. 
3. 

Actual Results:
meebey@redbull:~/tmp$ mdb test.exe
Mono Debugger
(mdb) run
Starting program: test.exe
Cannot read DWARF frame info from symbol file `/usr/bin/mono':
System.OverflowException: This isn't a 64bits machine.
in [0x0003c] System.IntPtr:.ctor (Int64 i64)
in [0x0008e] (at

(mdb) Cannot read DWARF frame info from symbol file

/home/meebey/data/projects/debian/pkg-mono/mono-debugger/mono-debugger-0.12/arch/Bfd.cs:624)
Mono.Debugger.Backends.Bfd:load_dwarf ()



Expected Results:
working debugging

How often does this happen? 
always, but when I retry it, the errors which symbol file it can't read
varies...
To me it sounds like it tries to read the files as I have a 64bit system
while I have a 32bit system (Pentium 4)
