I don't really *need* to extract data from this one, but why keep bugs? :)

What steps will reproduce the problem?
1. Linux Mint 16 Petra (64bit machine)
2. Download script & add exec rights to it
3. Run in command line:

    ./ccl_ssns.py ~/.config/google-chrome/Default/Current\ Tabs out.html

What is the expected output?

  Report generated, withot error.

What do you see instead?

What version of the product are you using? On what operating system?

   Current from trunk (master).  Linux Mint 16 Petra (64bit machine)

What steps will reproduce the problem?

attempting to parse chrome Current Session file extracted from hard drive using 
FTK imager

using following command:
user$ python ccl_ssns.py Current\ Session output.html

What is the expected output? What do you see instead?
gives error:

  File "ccl_ssns.py", line 713, in main

TypeError: 'encoding' is an invalid keyword argument for this function

What version of the product are you using? On what operating system?
latest build rev 4d96d3d2f2aa
running on ubuntu 12.04 precise
python version 2.7.3

Please provide any additional information below.
according to python documentation, only arguments for open() should be 
open(name[, mode[, buffering]])
there is no option for encoding

Despite shebang being python3, code is very close to working on python-2.7 and 
required only a few minor changes.

Fork with tweak: https://code.google.com/r/mkfraggod-py27-compat-fixes
Commit (just one new there):

I've tested result on local "Current Tabs" file with python 2.7.3 and 3.2.3, 
both seem to work with that commit added.

Not sure if maintaining py2.7 compatibility might be beyond the scope of 
project, but it just seem to be so trivial in this case.
Please let me know if you consider the change unnecessary, so I'll just 
clean-up the fork.

Thanks for sharing the script, really saved me a lot of time restoring a dozen 
tabs which one of the late chromium updates seem to have discarded.

Hi, great tool. I'd like to package it for Arch Linux.

Could you upload it to PyPI? That would make things easier.

1. Use Chrome 23 with several tabs, and exit uncleanly (e.g. kill the root 
Chrome process)
2. Run the script with "Current Session" (i.e. python python ccl_ssns.py 
"Current Session" "Current Session.html")
3. A "Current Session.html" file is not produced. Instead, an exception is 
raised: 

Traceback (most recent call last):

  File "ccl_ssns.py", line 326, in read_str_16
    char_count, = struct.unpack("<i", f.read(4))
struct.error: unpack requires a bytes object of length 4

This was done with the latest version of the script, and with Chrome 23.

The error occurs because at that point f.read(4) returns 0 bytes.

The last SessionCommand that is being parsed seems to be the following:

command_id=6 (245 bytes):
