From: glimmer07 Date: Wed, 22 Jul 2009 06:22:59 +0000 (+0000) Subject: Fixed GErrors. X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=fa0805ccb065538bb387363dbec791882e262b67;p=inkscape.git Fixed GErrors. Added many GErrors, especially for unfound objects. transfered many functions to using verbs instead of the function the verb calls to make error reporting easier. --- diff --git a/src/extension/dbus/dbus-init.cpp b/src/extension/dbus/dbus-init.cpp index a30bb8fda..dfd69d9fa 100644 --- a/src/extension/dbus/dbus-init.cpp +++ b/src/extension/dbus/dbus-init.cpp @@ -115,6 +115,9 @@ dbus_init_desktop_interface (SPDesktop * dt) DBusGConnection *connection;
