[Bug 291359] Re: Upgrade to Intrepid: kernel crash because of locales

[Moritz]

I faced the same bug on my AMD64 machine while installing lucid. What is
astonishing, that on random occasions the installing process can be
finished. After installing and updating todays language pack, this
happend and crashed my system (NO switching, NO typing possible)
