[PyQt] Eric4 buggy

[Mario Daniel Carugno]

Hi, i'm trying eric4 and seems too buggy.
Now i configure options, but every time i start Eric, configuration is
lost and i get the dialog:

"eric4 has not been configured yet. The configuration dialog will be started"

I tried with version 4.1 from debian testing, but also i've downloaded
the last version 4.3
Always the same thing

And eric was buggy in early versions too, sometimes it closes itself,
for instance.

Why is eric so buggy ? Do anybody know some 'stable' version of eric ?
