Missing mouse buttons

Thanks for the bug report, David. There seems to be a character encoding mismatch that only breaks Onboard in certain locales. I was already working on making sure those can't happen again, but unfortunaltely 0.96.1 is still affected.

Please be so kind, run onboard from a terminal and post the ouput. I suspect there will be a python backtrace that confirms this.
Also please post the ouput of 'locale'.

As a workaround, see if running onboard in english helps. This only changes the language of the user interface and won't affect your keyboard layout:
LANG=en_US.UTF-8 onboard

Thanks for your quick answer.

That's the output from the terminal:

david@david-M11JB:~$ onboard

If I open onboard from terminal and navigate (blindly) to the preferences icon the output is:

david@david-M11JB:~$ onboard

Thank you, this confirmed it. I'll see if I can get you another workaround.

What a surprise, today my PC shows the same problem! Output from terminal in my PC:

My PC was installed from the official release from ubuntu.com and it never had installed Italian language. This discard any relation with the Italian language and the 'unofficial' release. Maybe some recent update of oneiric broke onboard. A couple of days ago in a regular update the system several language packages were updated to 11.10+20120103 version:

language-pack-en
language-pack-en-base
language-pack-gnome-en
language-pack-gnome-en-base
language-pack-es
language-pack-es-base
language-pack-gnome-es
language-pack-gnome-es-base

Do you think that those language updates broke onboard? I don't know how can I revert those updates, oif you tell me I can test it.

Wish this helps. Thanks for you efforts, marmuta.

ok, so what appears to have happened is that language-pack-gnome-es-base has been updated recently, actually a couple of times starting at 2012-01-04.
https://launchpad.net/ubuntu/+source/language-pack-gnome-es-base/+publishinghistory
Some added translations for onboard in multiple languages replaced single quotes with double arrows, which most likeley triggered this bug. The blame is on onboard of course. We have to be prepared for anything utf-8 the translators give us.

This particular bug seems to affect only version 0.96.1. The current release 0.96.2(in Precise) had some messages upgraded to python 3 style formatting and doesn't appear vulnerable anymore. I'll do some more testing and then I think we should suggest another SRU for Oneiric.

Some workarounds:

Get onboard from the snapshot PPA, which currently is almost an 0.96.2:
$ sudo add-apt-repository ppa:onboard/snapshots

or run with the english user interface (2nd try):
$ LANGUAGE=en onboard

or, disable the spanish translation for onboard permanently (at least until language-pack-gnome-es-base is updated again):
$ sudo mv /usr/share/locale-langpack/es/LC_MESSAGES/onboard.mo{,_}

FYI: Onboard 0.96.2 for oneiric is available in the stable PPA:
https://launchpad.net/~onboard/+archive/stable

Run with the English user interface $ LANGUAGE=en onboard: IT WORKS!

Disable the Spanish translation $ sudo mv /usr/share/locale-langpack/es/LC_MESSAGES/onboard.mo{,_}: IT WORKS!

Get onboard 0.96.2 from stable PPA: IT WORKS!

I posted a problem on Friday and you give me 3 working solutions on Sunday. Thank you guys, you're great!
