Comment # 5 on bug 946923 from Dominique Leuenberger

from what I see it is linked to those '*curses*' libs:

ldd /usr/lib64/yui/libyui-ncurses.so.6 | grep curs
    libncursesw.so.6 => /lib64/libncursesw.so.6 (0x00007f5e63768000)


RPM added those dependencies:

libncursesw.so.6()(64bit)
libncursesw.so.6(NCURSESTW6_5.7.20081102)(64bit)
libncursesw.so.6(NCURSESTW6_5.8.20110226)(64bit)
libpanelw.so.6()(64bit)
libpanelw.so.6(NCURSESTW6_5.7.20081102)(64bit)

(as said: once I rebuilt libyui-ncurses against the curses 6.0 package, it
started working again.. so 'something' in this trace must have changed ABI)
