setting password crash

You should consider posting the version of wicd you are running there. and perhaps to update to the latest version.

And you should try this:
1- close wicd-client and terminate any running instance of it
2- open a terminal and write wicd-client
3- set the "password" and, once it freezes, check in the terminal if it gives you any messaged or error.

If there is a message/erro, post it here to be easier to help you.
If not, consider turning on the debug and try the same, this time, showing here the wicd log.

the version is 1.7.2.3

The terminal shows
