libssh2_channel_exec, LIBSSH2_ERROR_CHANNEL_REQUEST_DENIED error after second call

[S. Gurbel]

Hello!

In my program, I need to execute more commands in one channel. So I used the
example ssh2_exec and added second command execution.
Like this:
...
    libssh2_session_set_blocking(session, 1);

    channel = libssh2_channel_open_session(session);
    if( channel == NULL )
        exit(1);

    // first command executing -- changing a directory
    if(rc = libssh2_channel_exec(channel, "cd Projects")) {
        exit(1);
    }

    do {
    char buffer[0x4000];
        rc = libssh2_channel_read( channel, buffer, sizeof(buffer) );

        if( rc > 0 ) {

            int i;
            bytecount += rc;
            fprintf(stdout, "We read:\n");
            for( i=0; i < rc; ++i )
                fputc( buffer[i], stdout);

            fprintf(stdout, "\n");
        }
    } while( rc > 0 );

    // second command executing
    if( rc = libssh2_channel_exec(channel, "ls -l")) {
        exit(1);
    }

and here I get error LIBSSH2_ERROR_CHANNEL_REQUEST_DENIED.
I'm using libssh2-1.2.7 version on Ubuntu 10.04.

Thank you!
