This is how the lines around this look like. The removal of the line that starts with &driverState->pools is also wrong and I did not re-format that one, either (using quilt). I am using Thunderbird 3.3.1.

-    nwfilterDriverLock(driverState);
-    virNWFilterPoolLoadAllConfigs(NULL,
- &driverState->pools,
-                                  driverState->configDir);
-    nwfilterDriverUnlock(driverState);
+    conn = virConnectOpen("qemu:///system");
+    if (conn) {
+        /* shut down all threads -- qemud for example will restart them */
+        virNWFilterLearnThreadsTerminate(true);
+        nwfilterDriverLock(driverState);
+        virNWFilterPoolLoadAllConfigs(conn,
+ &driverState->pools,
+                                      driverState->configDir);
+        nwfilterDriverUnlock(driverState);
+        virConnectClose(conn);
+    }

Since this is an libvirtd-internal call I suppose qemu:///system should be alright... I'll wait to hear from Dan then.
