[Pkg-utopia-maintainers] Bug#814906: network-manager-pptp: PPTP fails to obtain secret second time on 1.1.90

[Vladimir Kudrya]

Package: network-manager-pptp
Version: 1.1.90-2
Severity: normal

Dear Maintainer, after upgrade of NM to version 1.1.90 PPTP connection started
to fail if trying to bring it up second time. This error shows up in the log:

Feb 16 14:58:46 hostname NetworkManager[31651]: ** Message: nm-pptp-ppp-plugin: (nm_phasechange): status 6 / phase 'authenticate'

Secret is stored globally in connection profile. Fist attempt is usually
successful, but reconnect fails. Killing nm-pptp-service fixes the problem for
next time.

nm-pptp-service process persists after PPTP connection is down. Is it normal?
