Hi! I'm trying to debug what appears to be an issue in libsignon-glib, which is used in the signon backend. In order to debug it, I need to see the output of the g_debug() calls happening inside that library, but for some reason I can see only one of them: ============== $ G_MESSAGES_DEBUG=all SYNCEVOLUTION_DEBUG=1 syncevolution loglevel=1 --daemon=no --sync two-way google-100 ...sources... [DEBUG 00:00:00] log path -> /home/phablet/.cache/syncevolution, <okay> [DEBUG 00:00:00] checking log dir /home/phablet/.cache/syncevolution [DEBUG 00:00:00] logfile: /home/phablet/.cache/syncevolution/google_+100-2016-06-29-18-04/syncevolution-log.html [DEBUG syncevo-local-sync 00:00:00] ForkExecChild: connecting to parent with D-Bus address 11 [DEBUG syncevo-local-sync 00:00:00] child connected to parent [ERROR @google-100] error code from SyncEvolution access denied (remote, status 403): could not obtain OAuth2 token: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name :1.135 was not provided by any .service files [ERROR @google-100] error code from SyncEvolution access denied (remote, status 403): logging into remote service failed: error code from SyncEvolution access denied (remote, status 403): could not obtain OAuth2 token: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name :1.135 was not provided by any .service files [DEBUG @google-100 00:00:18] signon-identity.c:636: identity_session_object_destroyed_cb 636 [ERROR] error code from SyncEvolution access denied (remote, status 403): failure on target side @google-100 of local sync: could not obtain OAuth2 token: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name :1.135 was not provided by any .service files ============== As you can see, in the logs above there *is* a line coming from libsignon-glib, but only one, while all the others (which I'm sure are being executed, and they are all calls to g_debug()) are not visible. Any idea of what could be the reason? Ciao, Alberto
