Comment 9 for bug 1622571

I believe I'm also having this problem. I've uploaded the whoopsie dump with apport but I can't see where it is being tracked (see http://askubuntu.com/questions/900191/where-do-i-look-to-see-if-my-whoopsie-is-being-tracked).

The stack looks the same:

This started happening when I commented out the dns=dnsmasq line in my NetworkManager.conf and indeed the crash happens in DNS related code.

The often occurs after resuming from suspend, but not always - it may also just occur while using the host.

Here's a link to the whoopise upload - I don't have perms to see it, but perhaps someone who does can associate it with this bug?
