unhandable error when installing Virtual Box .deb in 10.10 Ubuntu Software Centre

[Zam Olxis]

I downloaded Virtual Box latest version .deb (non-OSE), saved it on a network share, then right click in Nautilus and chose "install in Ubuntu Software Center". I got this:

Traceback (most recent call last):
  File "/usr/lib/python2.6/dist-packages/aptdaemon/worker.py", line 768, in simulate

1. I then tried installing by right-click -> GDebi and after authenticating as root I got "file does not exist"
2. Copied file to desktop
3. right-click -> install with USC again -> started but close to the end got the same error but w/o details (see screencap attached)
4. right-click -> install with GDebi -> started, had the "close on finish" checkbox checked, seems to finish uneventfully but no error and no install
5. added deb http://download.virtualbox.org/virtualbox/debian maverick non-free to repositories via Synaptic
6. error message on reload - the SRC had been incorrectly added as well (SHOULD THIS BE A SEPARATE BUG?)
7. unchecked the SRC entry in repositories, then sudo apt-get install virtualbox-3.2
8. SUCCESS!

I got the same thing installing from a network share. I saved the Revenge of the Titans deb-file (humble indie bundle, humblebundle.com, games working on linux) to a network share and tried to install from there.

Traceback (most recent call last):

    self._debfile = apt_inst.DebFile(open(self.filename))
IOError: [Errno 13] Permission denied: '/home/dutchy/.gvfs/dutchy on dragon/documents/RevengeOfTheTitans-HIB-amd64.deb'

I then copied the file to a local disk and got a different error, but no traceback:

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.

I have no idea if the deb package was meant for Ubuntu though.
