With no application in use I started Remmina to connect to another Linux-Box. No conextion was set up -> timeout.

Start of "Network" from the Dash, click on Network proxy -> after 3 - 5 seconds crash of "Network" / closed the window.

Now with Firefox writing this words ...... I tried to open "Network" and it is possible to switch between "Wired" and "Network proxy" to see the information.
Now on the same time I started Remmina to try to connect like before. But now the main Window is gray (overload?) and the little "Connecting to ..." window is open but you can't use the Cancel button.

On the "Network" Window selected "Wired" the Options.... -Button is deactivated.
After an CLOSE and OPEN "Network" the Options... -Button is active again.

To close the Remmina Window you have to click on the close button of the main window and use the Force Quit in the upcomming window.

I install iso of 21 of march (downloaded 12:15).
Open "Network" from Dash. Tried to click on all active fields to change indications. All seems to be OK.
On the same window click on "All applications" and start again the "Network". Try to click al active items. Click on "All applications". And so on ...
Three or four times and the next click on "Network" caused the crash.

Tedesco,

Are you still able to reproduce this crash? Seems to me like any crash in nm_device_get_udi() should have been fixed now (it's been fixed for a while in theory). It would be useful if you could comment back on this.

Thanks!
