It also happened to me. Don't worry since it can be resolved by removing appmenu-qt and appmenu-qt5. Those packages (appmenu-qt and appmenu-qt5) won't be needed since you are using Gnome 3.
I attached a screenshot of the result after appmenu-qt and appmenu-qt5 got removed. ** Attachment added: "Screenshot" https://bugs.launchpad.net/ubuntu/+source/qtcreator/+bug/1308159/+attachment/4086939/+files/qtcreator.png -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to qtcreator in Ubuntu. https://bugs.launchpad.net/bugs/1308159 Title: QtCreator shows no main menu in gnome3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qtcreator/+bug/1308159/+subscriptions -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
