Comment 1 Will Stephenson 2009-08-17 07:54:46 UTC

SVN commit 1012196 by wstephens:

Fix another unchecked pointer crash.  This comes from coding blind.
OTOH where the crash occurred indicates that the VPNC connection was
brought up successfully.  Please test

Comment 2 Gregor Petrin 2009-08-17 09:02:25 UTC

Thanks for the very quick response, I will test it as soon as I am able.

Comment 3 Gregor Petrin 2009-08-25 10:34:39 UTC

I tested the connection and there was no crash, so the fix was successful.

But I couldn't find the VPN connection (i.e. by using the command 'ip addr') and I couldn't ping any VPN addresses.. anyway, I didn't have too much time to play with it yet, so just consider this specific bug report as confirmed resolved :)

Comment 4 Will Stephenson 2009-08-30 11:16:30 UTC

Use bug #188489 for general VPNC connection problems, now the crash is fixed.
