Created an attachment (id=258433)
 --> (https://bugzilla.novell.com/attachment.cgi?id=258433)
y2log from both unsuccessful (qt) and successful (ncurses) scanner setup

This might be related to bug 439431 about yast2 printer hanging.

I also googled and found another recent report from an openSUSE-11.0 user with
the same problem:
http://linux.derkeiler.com/Mailing-Lists/SuSE/2008-11/msg01862.html

yast2 scanner calls
/usr/lib/YaST2/bin/y2base scanner -S qt
changes caption to "Scanner Model and Driver Selection"
and then hangs in busy loop (100% CPU)

an interesting bit of information:
yast scanner which calls
/usr/lib/YaST2/bin/y2base scanner -S ncurses
works

I used gdb and hit Ctrl+C to find where it hangs:
Program received signal SIGINT, Interrupt.
