Cannot redeclare class phpdocumentor\reflection\docblock\tag\methodtag

I get the following error when trying to execute phpunit within PhpStorm:

Fatal error: require(): Cannot redeclare class phpdocumentor\reflection\docblock\tag\methodtag in /home/hhl/public_html/posthus/_intellij_phpunit_launcher.php(194) : eval()'d code on line 457

    $execute = true;
} else {
    $execute = false;
}

When making the same on the remote server, everything is working fine.

I use PhpStorm 10.0.1 on windows 7.  My remote server is a Debian 6.   php version: 5.3.3.  phpunit version: tried many 4-8 latest (phar version).

Is there somebody who can give me some good advice
