[Bug 1404188] Re: QNetworkSession::isOpen() always returns false

 

Looks like an app armour thing.

Debug-helper> Executing /usr/bin/qmlscene['/usr/bin/qmlscene', '$@', 'share/qml/nmsessiontest/nmsessiontest.qml']

UbuntuClipboard - Got invalid serialized mime data. Ignoring it.

There was another bug mentioning that abstract dbus interface does not introspect, whereas QDBusInterface does
QDBusInterface is used all over in the nm QtBearer plugin.

Title:
  QNetworkSession::isOpen() always returns false

Status in qtbase-opensource-src package in Ubuntu:
  New

Bug description:
  Using QNetworkSession::isOpen() in confined apps on a phone running
  vivid always returns false. This might be an apparmor thing, however,
  I couldn't find any REJECTED entries in log files.

  The test app in lp:~mzanetti/+junk/nmsessiontest can reproduce the
  issue. Open this project in ubuntu-sdk's qtcreator and run it on a
  vivid device. Press the button and watch the debug prints.

  On a vivid-desktop or a RTM based phone it will print "all is well".
  On a vivid phone however, it'll print "network session not open..."

  This used to work fine at least back in utopic images.
