Subject: [PATCH] libnm-glib: fix crash by taking additional ref in
nm-remote-connection/result_cb
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
result_cb invokes a function pointer provided by the user. Nothing prevents
the user from destroying the NMRemoteConnection in the callback, which leads
to a crash. Take an additional ref of NMRemoteConnection to keep it
alive.
This probably caused a crash for nm-applet:
