Description of problem:

While trying to create valgrind report for bug 1128766  valgrind spoted read
from already released memory  (while using VPN plugin to access VPN for the second time)

Here is short cut&paste

Comment 7 Zdenek Kabelac 2016-01-31 18:30:36 UTC

Wondering if the but is already fixed in rawhide package?

network-manager-applet-1.2.0-0.2.beta1.fc24.x86_64


From debug package source it seems so - yet I've still get new nm-applet crash:

Which looks like reincarnation of the same issue?

with very simple use-case scenario:

Disconnect in office  wired network via docking station in suspend,
resume at home & connect to wireless and fire   'OpenVPN'  connnection.

As a 'bonus' for version 0.3 I'm getting 'black' background for nm-applet on my otherwise light colored  xfce4 panel...


Switching back to new as still not resolved.
