thunderbird can't be default e-mail client

[Diane V]

Binary package hint: thunderbird

Ubuntu 8.04
thunderbird:
  Installé : 2.0.0.14+nobinonly-0ubuntu0.8.04.1

Wanted thunderbird as default e-mail client, filled the box to check that at launch, an ask check now.
It doesn't check, neither now nor at launch, and evolution remains the default.

Thank you for your work. Bye.
