Here are reliable steps to reproduce. Seems only to happen after using the messaging-app:
First load the pulseaudio image: phablet-flash cdimage-touch --pending --ubuntu-path http://10.97.2.10:8080/job/ubuntu-touch-image-saucy-pulseaudio/lastSuccessfulBuild/artifact/saucy-preinstalled-phablet-armhf.zip Then remove phone-app: sudo apt-get purge phone-app Then install from amanzi-team/testing ppa: sudo apt-get install dialer-app messaging-app Reboot Then do this: 1) make multiple outgoing calls (10 calls) from dialer-app, hanging up before it is answered . should all work 2) launch messaging-app, send one text message, and receive one text message from another phone 3) go back to dialer-app 4) repeat step 1, will start to not be able to hangup -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1208869 Title: [Dialer app] End call button is not responsive To manage notifications about this bug go to: https://bugs.launchpad.net/dialer-app/+bug/1208869/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
