Nokia :: 5800 XM - Probable Bug With EAP - TTLS Plug In WPA / WPA2

While adding a WPA/WPA2 access point and trying to setting the EAP-TTLS plugin, the setup window suddenly closes without saving the settings. It is impossible to connect a WPA/WPA2 wireless network that uses EAP-TTLS plugin for authentication/cryptation. All other plugins work fine. The current software version is 40.0.005 (40.0.005.C01.01) - 29-12-2009. It is worth noticing that with the previous sw version (I don't remember the number, maybe something like 31...), all worked well. Once I updated the sw, my WPA access point ceased to work, and I found out the problem.
