<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hi,    I am trying to use the geoclue library, but I cannot launch any position providers by using master provider. When master provider checks the usable provider, it will crash.  Following is the error info when manually start master provider. GLib-GObject-CRITICAL **: g_type_instance_get_private: assertion `instance != NULL && instance->g_class != NULL' failed [1]+  Segmentation fault      /usr/libexec/geoclue-master I look into the src/master-provider.c +125 in gc_master_provider_get_provider() function and change the address to position, then it works. has anyone met this problem? is this a bug?  or something wrong with my configuration? 2. when I open the DEBUG_INFO macro before configure, there will be an error when compiling: master-provider.c: In function ‘gc_master_provider_dump_provider_details’: master-provider.c:725: error: ‘master_provider’ undeclared (first use in this function) This should be changed to "provider" to pass compilation,  dose it a bug? All above are based on geoclue-0.11.1. Thanks very much. </td></tr></table> <hr size=1><a href="http://cn.rd.yahoo.com/mail_cn/tagline/card/*http://card.mail.cn.yahoo.com/"> 好玩贺卡等你发，邮箱贺卡全新上线！</a>
