problem with external programs

["F. Heitkamp" <heitkamp@xxxxxxxxxxxxx>]

I am having a strange problem with mutt.  I have configured mutt to use 
"less" as the external pager, vim as the editor and "lynx" to view html 
files.  Neither of these options work for me.  What appears to be 
happening is that the temporary file (tempfile) is getting deleted before 
the external program can use it or the tempfile name is incorrect. For 
example the tempfile is "mutt-pc1-24395-68" but the external program wants 
"mutt-pc1-24395-69". I have discovered this by putting some debugging 
statements in system.c and and command.c.  It's strange that the builtin 
pager works OK though.

In more detail one of the changes I made is that I have changed 
mutt_system a bit to:

    err_ret = execl (EXECSHELL, "sh", "-c", cmd, NULL);
    if( err_ret == -1 )
    {
        sprintf( buff, "Error executing \"%s\"", cmd );
        perror(buff);
    }

When I run mutt invoking vim I get.
Error executing "/usr/bin/vim '/tmp/mutt-pc1-24854-1'": No such file or 
directory

I am using kernel 2.6.8-rc3, gcc version 3.4.2 20040818 (prerelease) and 
glibc 2.3.3
