Error submitting a bug on firefox-trunk on Ubuntu Noble

When you search for the mentioned package, it does not show up for Noble.

https://launchpad.net/ubuntu/noble/+search?text=firefox&batch=200&memo=75&start=0

The error message in the log looks like

```
lp.bugs.interfaces.bugtask.IllegalTarget: Package firefox-trunk not published in Ubuntu
```

The PPA I used seems just for Noble:
corrado@corrado-n2-nn-1029:~$ apt policy firefox-trunk

PPAs aren't part of Ubuntu. Bugs in PPA packages need to be reported by contacting the PPA owner.

My bug is about Launchpad crash, not about firefox PPA
if the PPA is bad launcpad should report the problen on PPA bud should not crash.
