[ubuntu-dev] Bug#768193: gdebi-kde: Fails to install package with message "package file does not exist"

[Chris Ure]

Package: gdebi-kde
Version: 0.9.5.5+nmu1
Followup-For: Bug #768193

Dear Maintainer,

   * What led up to the situation?
Attempted to install .deb package via gdebi-kde.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
Invoked gdebi-kde through dolphin context menu on
~chris/Downloads/dropbox_1.6.2_amd64.deb as non-root user.

   * What was the outcome of this action?
Gdebi-kde started correctly. When Install Package button is selected, gdebi
exits and invokes kdesu with command "/usr/bin/gdebi-kde -- -n
/home/chris/Downloads/dropbox_1.6.2_amd64.deb". after entering correct root
password, the error message pops up and, upon confirmation, exits the program
with error code 1.

   * What outcome did you expect instead?
I expected the package to still be recognized after kdesu grants the program
root privileges.

Additional info:
Appears to only be an issue when ran as non-root user, e.g. through kdesu.
