I can reproduce this with:
$ mkdir /tmp/ää
$ cd /tmp/ää
$ apt-get download 2vcard
$ software-center /tmp/ää/2vcard*.deb
this will also give me a crash.

I can't install Google Chrome amd 64 deb if I place it in Desktop folder. I think problem with cyrillic name of Desktop folder as "Рабочий стол". If I remove deb file to home directory it installs ok.

I tryed to install google-chrome-beta_current_amd64.deb

This one's not actually fixed released as it is still appearing on errors.ubuntu.com.

[Nicolas Delvaux (malizor)]

There are actually 2 bugs.

- LP: #1058038 installation of a def file inside a unicode-named folder crash
- This bug : when double clicking on a deb file inside of a unicode-named folder *when software-center is already launched*, an error appears (before even clicking on install)

I can't install Google Chrome amd 64 deb if I place it in Desktop folder. I think problem with cyrillic name of Desktop folder as "桌面".

[Michael Vogt (mvo)]

I can reproduce this with:
$ mkdir /tmp/äää
$ (cd /tmp/äää ; apt-get download 2vcard)
$ software-center /tmp/äää/2vcard*.deb

click on "install" and authenticate:

@Michael Vogt: you reproduced LP: #1058038, not this one.

To reproduce this particular bug, launch the software-center and then double click on the deb file you just downloaded in /tmp/äää.

This is not the same bug because the "workaround" I proposed for LP: #1058038 (launching aptd from the command line) does not workaround this one. And backtraces are diffrent.

[Michael Vogt (mvo)]

Ignore my previous comment, its for #1058038

To reproduce this one:
$ mkdir /tmp/äää
$ (cd /tmp/äää ; apt-get download 2vcard)
$ software-center
[wait until its open]
[in a different terminal:
$ software-center /tmp/äää/2vcard*.deb

The attached branch lp:~mvo/software-center/lp1043752 fixes this.

[Launchpad Janitor (janitor)]

This bug was fixed in the package software-center - 5.4.1

[Matthias Gehre (m-gehre)]

I just encountered this bug today. (At least apport tells me that it is exactly this bug.)
I'm not aware of any unicode issue, though, and I'm running latest raring
with software-center 5.6.0-0ubuntu2.
