Please can you elaborate on the use case?
I suppose you were connected on at least one port + refresh ports list.
Do you reproduce it easily?

I reproduced the error in this way:
attached a fastrack
pressed the connection button (it appears in the console port opened)
pressed refresh on ports -> appears first error and a port disappear
pressed refresh on ports again -> appears the error again and all ports disappear

on ubuntu 64

Ok, thanks for the details: we’re going to have a look.

the bug is still present with studio 2.0.0

daav · April 8, 2011, 7:13am

We’ve concentrated our effort on new debugging solution in 2.0.0, and didn’t take the time to look at this. However we’ve planned to allocate more time in the next release development to consider all the feedbacks reported here!
