OpenVPN can't restart after Inactivity timeout

[GoogleCodeExporter]

What steps will reproduce the problem?
1. OpenVPN is always connected 24/24 on the vpn server
2. Sometimes (may be few times a week or month), the server does not answer (or 
my internet access does not access to the server) and the connection timeout.
3. OpenVPN detect the loss of connection due to timeout, and try to restart the 
connection but crash.
4. Click manually on "Connect" restart the connection correctly.

What is the expected output?
OpenVPN restart the connection and connection come back.

What do you see instead?
The client.down.tunnelblick.sh script crash at the restart so the connection 
never come back.

What version of Tunnelblick are you using? On what version of OS X?
3.1beta12 (build 1998), on Snow Leopard 10.6.4.

Please provide any additional information below. Please include your
configuration file and the contents of the OpenVPN Log window (including
the first few lines with version information), but remember to remove any
sensitive information such as IP addresses.

Here are the logs where it fails:

Thanks for your report. This looks like a straightforward bug in Tunnelblick's 
standard "down" script. Try replacing the existing

/Applications/Tunnelblick.app/Contents/Resources/client.down.tunnelblick.sh

with the attached version.

Please respond here if this solves the problem, and I will incorporate this 
change into the source code so it will be in the next release.

Notes:

(1) To open a Finder window containing Tunnelblick.app, right-click (or 
control-click) on

/Applications/Tunnelblick.app

and click on "Show Package Contents".

(2) You will have to "Authenticate", using a computer administrator's username 
and password, to replace client.down.tunnelblick.sh if Tunnelblick has been run 
because the first time Tunnelblick was run it changed the ownership and 
permissions of that file.

(3) The first time you run Tunnelblick after replacing 
client.down.tunnelblick.sh, you will be asked for a computer administrator's 
username and password, so Tunnelblick can change the ownership and permissions 
of the new version of the file.

I think it solves the problem, at least when I simulate a down of the vpn 
server and then restart it, the .sh script does not crash and the connection 
come back correctly.

I will tell you if I have an other case where it could crash if it does it 
again.

Thanks

Thanks for the update.

If I don't hear anything else I'll commit the changes to the source code early 
next week.
