crashes when installing packages from non ascii folders

Same with:
gpk-install-local-file töölaud/themonospot_0.7.1.1-1~getdeb2_all.deb

I can confirm this. But on my system, when i install a package from a Chinese folder, Kpackagekit just says that it can't find the package. The error output is misleading.

Hi,

Estobuntu team fixed the problem!

Lauri Võsandi

Could Savvas Radevic and Jimhu or others who have had the same problem please confirm whether this patch works or not?
Thankyou!

I tried it and it works. It's quite trivial (for a developer) to test it. :)
These are the steps for gnome:

sudo apt-get -y install packagekit-gnome
cd
wget http://launchpadlibrarian.net/26683813/packagekit-utf8-fix.patch -O packagekit-utf8-fix.patch
cd /usr/lib
sudo patch -p0 < $HOME/packagekit-utf8-fix.patch

cd
mkdir -p "töölaud"
wget http://http.us.debian.org/debian/pool/main/t/themonospot/themonospot_0.7.1.1-2_all.deb -O "töölaud/themonospot_0.7.1.1-2_all.deb"
gpk-install-local-file "töölaud/themonospot_0.7.1.1-2_all.deb"

This bug was fixed in the package packagekit - 0.4.9+20090825-0ubuntu1

---------------
packagekit (0.4.9+20090825-0ubuntu1) karmic; urgency=low

  * New upstream snapshot provding a lot of APT backend improvements:
    - Allow to install updates which require the installation of additional
      packages. Updates depending on the removal of a package are still
      blocked (LP: #342671, LP: #374011, LP: #374011)
    - Warn about the installation of untrusted package (LP: #256245)
    - Don't crash in APT post update hook if system D-Bus daemon isn't
      running (LP: #388623)
    - Don't try to estimate a download progress during cache updating, since
      APT reports only a forth- and backwards running progress. (LP: #348053)
    - Support for python-apt 0.7.12 (LP: #415993)
    - Translated package descriptions
  * debian/patches:
    - Remove ignore_packages_in_conffile (Merged upstream)
    - Remove fix_typo (Merged upstream)
    - Add fix_unicode: Handle the encoding messages via stdin/stdout correctly
      (LP: #396513)
    - Add fix_unicode_debfile: Convert the path of the local file which
      should be installed to the correct encoding (LP: #347327)
  * debian/libpackagekit-qt-dev.install: Fix install location of CMake module.
    Thanks to Sveinung Kvilhaugsvik (LP: #345706)
  * debian/control: Fix spelling of Qt. Thanks to Sveinung Kvilhaugsvik
    (LP: #378419)
