- In a live environment (32-bits), I cannot add a wireless connection. This
results in a "Insufficient privileges" message.
- Live user has root permissions.
- Distribution based on Debian Testing.
- No wpa_supplicant logs are created.
- I cannot confirm this happening on a 64-bit system.
- Once installed I have no problem making new wireless connections.

Reproducible: Always

Steps to Reproduce:
1. Download and run from USB: http://www.schoelje.nl/lmdekde/lmdekde32_up5_20120929.iso
2. Open Network Management Settings
3. Add a wireless connection
Actual Results:  
Error message: 
error adding connections: Insufficient privileges

Expected Results:  
Even in a live environment I expect to be able to create a wireless connection.
