VLC fails to start in Ubuntu 10.10

[ds4h]

There is this problem I've had for a few days now. All my attempts to solve this were fruitless so far, hence, I'm posting it here.

In short, vlc fails to start. It was working with Ubuntu 10.10 happily until a few days ago it just stopped running at all.
* When i click on the VLC icon in Applications menu, it attemptls to load, interface shows up briefly and exits immediatelly.
* When i type 'vlc' in terminal, behavior same as above, and the output is:

What I've tried so far: reinstalled numerous times through Ubuntu software center/synaptic/apt-get; followed guidelines in viewtopic.php?f=13&t=70719; searched these forums for an answer, no luck so far.

Any pointers to the solution would be appreciated.

Did you update any OTHER library that VLC uses? There seems to be something fishy with GTK there...

You can always try to reset VLC (vlc --reset-config --reset-plugins-cache).

I'm not entirely sure if I updated something else or not, as the player broke a few days ago (yes, I'm an airhead, I know). However, after the reset command, I can now use it as normal. It's fixed for now, thank you for a hint.

Ack it was broken for me too...
I wiped out config/vlc and am reconfiguring...
The problem seems to be when "skinnable" is selected _and_ "extra interface" skins 2 also is selected...
Did something change with "skinnable" "skins2" support?
It won't start when they are both selected, but that is what was working before...
