svnmanager1.10： VersionControl_SVN_Exception: "svn_path" is not a valid option

svnmanager1.10安装完毕后，选择“Repository Admin"-->"Group Privileges",会出现repository的列表，选择其中一个”Select"后，会出现如下错误：

VersionControl_SVN_Exception: "svn_path" is not a valid option

#0 /usr/local/php/lib/php/VersionControl/SVN.php(267): VersionControl_SVN_Command->setOptions(Array)

#1 /usr/local/php/lib/php/VersionControl/SVN.php(226): VersionControl_SVN::init('list', Array)

#2 /opt/apps/web/php/svnmanager/svnmanager/RepositoryModule/GroupPrivilegesEditPage.php(214): VersionControl_SVN::factory(Array, Array)

#3 /opt/apps/web/php/svnmanager/prado-2.0.3/framework/Web/UI/TControl.php(419): GroupPrivilegesEditPage->onLoad(Object(TEventParameter))

#4 /opt/apps/web/php/svnmanager/prado-2.0.3/framework/Web/UI/TPage.php(1079): TControl->onLoadRecursive(Object(TEventParameter))

#5 /opt/apps/web/php/svnmanager/prado-2.0.3/framework/Web/UI/TPage.php(955): TPage->onLoadRecursive(Object(TEventParameter))

#6 /opt/apps/web/php/svnmanager/prado-2.0.3/framework/TApplication.php(483): TPage->execute()

#7 /opt/apps/web/php/svnmanager/index.php(5): TApplication->run()

#8 {main}

解决方法是编辑/var/www/html/svnmanager/svnmanager/RepositoryModule目录下的

UserPrivilegesEditPage.php 和 GroupPrivilegesEditPage.php 文件 :
$options = array('fetchmode' => VERSIONCONTROL_SVN_FETCHMODE_ARRAY, 'svn_path' => $svn_cmd);
改成:
$options = array('fetchmode' => VERSIONCONTROL_SVN_FETCHMODE_ARRAY);
目前程序运行良好，但是不知道以后是否会有问题。
