The old version worked fine. APPORT did catch a crash but I am wary of uploading it since it may have contained my private key password...

Thanks for reporting this issue.

Could you please trigger the crash, let it collect information but do not report it to the bug tracker. This will leave a file in /var/crash which should not contain sensitive data (it's a textfile so you could easily look over it). I desperately need more information on this issue. I did a few patches which improved the expirience for me, but I don't know yet what causes your crash.

Philipp,

Actually the crash was still sitting in /var/crash so here it is. Hopefully this will help.

Thanks!

Ok, I think I got the problem. I will prepare an upload in a few hours (the offending patch is 06_pull_dns_domain.diff).

A fixed package is on its way to the publisher. Please test the new version and report if it still causes problems. The problem was some incorrect string handling when no search domain was sent by the server.

Thanks Philipp,

Just updated network-manager-openvpn now and all seem to come back to the right way, since I'm now connected to my office properly.
