in software center,when clicking install button it crashes

[marcandrebenoit]

i went to google chrome's website to download the .deb to install chrome with..
when the download is finished i see that instead of opening with the debian installer it offers to open with software center..
it takes a few seconds,greys out a little then shows the software center with chrome stable setup page with install button.
and sentence saying "only install of source is trusted" and install button next to it..

when pressing the button ,software center crashes and spits out the following:

An unhandlable error occured.
There seems to be a programming error in aptdaemon, the software that allows you to install/remove software and to perform other package management related tasks. Please report this error at http://launchpad.net/aptdaemon/+filebug and retry.

it then goes on saying in the details section:
Traceback (most recent call last):
  File "/usr/lib/python2.6/dist-packages/aptdaemon/worker.py", line 765, in simulate
    return self._simulate_helper(trans, status_path)
  File "/usr/lib/python2.6/dist-packages/aptdaemon/worker.py", line 837, in _simulate_helper
    deb = apt.debfile.DebPackage(trans.kwargs["path"], self._cache)

    self.open(filename)
  File "/usr/lib/python2.6/dist-packages/apt/debfile.py", line 66, in open
    self._debfile = apt_inst.DebFile(open(self.filename))
IOError: [Errno 2] No such file or directory: dbus.String(u'/tmp/google-chrome-stable_current_amd64.deb')

the system was just installed a few hours ago,and after the partial upgrade (system is now said to be up to date)
was done through update manager,i was planning on installing chrome as a first order of business :)

i hope this helps you out,i'll now try again to see what gives...
