Arch Linux

Description correction:
nm-applet core dump on connect; ...

Connection stays active.

Not only in Xfce, but in `stalonetray`.

More ways to reproduce:

1. Left click the icon to show the network list; if nm-applet do not crash at this point, you can left click again to hide the menu, and:
a) Left click again. It crash.
b) Right click. It crash.

$ strace -o strace.log nm-applet
Segmentation fault (core dumped)

Left click on icon.
Select wifi id from menu.
Crash.
nm-applet icon disappears.
Connection stays active.

I also have this issue on XFCE. Interacting with the right click menu does not cause it to crash. Only left clicking it twice to show and hide the menu causes a crash for me.

I've downgraded to 1.8.11dev+12+ga37483c1-1 in the meantime which fixes the problem for me.

Same issue on i3

Unlike the others, mine crashed without having to click it. After resuming from suspend or during normal operations.

Crash is related to listing wifi-networks. If wifi is disabled nm-applet will not crash.

Same here, crashes either while listing networks or even after a while running. Last trace:

XFCE, network-manager-applet-1.8.12-1,
- segfault after clicking on the Wifi SSID
- segfault after right clicking on the applet

Trace is the same as Alex Ellwein (ElVino).

Please try 1.8.12-2.

I can confirm 1.8.12-2 works for me and doesn't bail out anymore.
