Plasma applet shows IPv4 address even after it is disabled and only IPv6 is configured in NM and on interface.
Steps to Reproduce:
1. Configure IPv4 connection in NM profile and connect to network.
2. Disable IPv4 in configuration and enable IPv6. Reconnect to network.
3. Look at network interface details at Plasma Applet and compare it with "ip address".
Plasma Applet shows IPv4 address (and no IPv6 address which is reported as bug #311832).
"ip address" shows no IPv4 address, only two IPv6.
Plasma Applet shows IPv4 address when it is really configured on interface.
When I remove and reinsert network driver kernel module and reconnect, Plasma Applet shows no address.
because of bug https://bugs.kde.org/show_bug.cgi?id=311894, which I have just fixed, it was not possible to really disable IPv4 in Plasma NM. What Plasma NM do you use? You can see the version string in "Manage Connections" -> "Other". Bug #311832 is a duplicate of bug #276110.
Version 0.9.0.5 (nm09 20121206)
I can still reproduce it.
Well, this bug will be fixed in Plasma NM 0.9.0.7, which I have not relesead yet. I will release it next weekend.
