For the record, when I trapped the error that was causing the crash, this is the message it gave:
CreateSecureDevice failed with error := 4; Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. -- bluetooth-properties crashed with signal 5 while adding HID device https://bugs.launchpad.net/bugs/179399 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
