I have the same problem: It seems to be wireless related somehow

Description of problem:

The (live-cd) installer won't go passed the language selection screen when continue is pressed, regarding the choice of language. The problem disappears when the wifi-adapter is disabled/unplugged.

Version-Release number of selected component (if applicable):

anaconda 18.37.11 for Fedora 18 

How reproducible:

Reproducible

Steps to Reproduce:
On my laptop (Lenovo x301) there is a hardware wifi switch (on the back).

Case A:
1. if I boot with the wifi on, 
2. lauch the installer (either with the on login presented button) or with /usr/bin/liveinst)
3. Press continue --> nothing seems to happen

Case B:
1. if I boot with the wifi off, 
2. lauch the installer
3. Press continue --> everything seems ok

Case A (wifi on) throws these errors to the terminal:

[liveuser@localhost ~]$ /usr/bin/liveinst 
localuser:root being added to access control list
Starting installer, one moment...
anaconda 18.37.11 for Fedora 18 started.

This seems like a duplicate of bug #893892 (wwan device is involved?), I'd like to see /tmp/anaconda-tb* to be sure.

You can check a fix from https://bugzilla.redhat.com/show_bug.cgi?id=893892#c10.

Created attachment 679429 [details]

Jann, your case is really a dupe of #893992.

That's solved then, maybe a good idea to add this bug to:
https://fedoraproject.org/wiki/Common_F18_bugs

True, I'm handling it in the original #893892.
