log: unpack crx file with chrome

1. Download the Chrome installer from
http://www.google.com/chrome?platform=win&hl=en

2. make sure bug 14864 is fixed, install Chrome:
wine-1.3.20-230-g456e48e

$ wine ChromeSetup.exe

3. start chrome with --no-sandbox 
==
without --no-sandbox, chrome can not open any web site. is this a know bug? or
should I submit a separate bug?
==

$ wine chrome.exe --no-sandbox

4. open
https://chrome.google.com/webstore/detail/faamegfkmmdnkpdipihbehibalfjpmpk ,
install the theme package .
then there will be a message box says:

Can not unpack extension.  To safely unpack an extension, there must be a path
to your profile directory that starts with a drive letter and does not contain
a junction, mount point, or symlink.  No such path exists for your profile.

full log is attached .
