Ok, I managed to reproduce the crash after running a nostrip --no-daemon NetworkManager

The steps to reproduce:
0) the network you intent to connect to must not have its password cached (not sure if it matters if 
the network really exists)
1) start NM and see what networks are present (I used both the applet and the nm-tool), your tested 
one must not be visible
2) try to forcefully (Connect to Other Networks) connect to a network which has WPA-Personal, but is 
unreachable --- provide the correct password, too
3) try once more to connect to the same network, now though the gnome applet menu -- now the network 
should be listed with no signal
4) crash

The log of NM and the backtrace are attached.




I suspect that the main reason for the crash is that NM gets confused and tries to use the password 
it was given before, but that was not stored.
