Version:           4.1.86+svn902162 (using Devel)
OS:                Linux
Installed from:    Compiled sources

I'm currently testing SVN snapshot 4.1.86+svn902162 packages from kde42.debian.net.
I'm having troubles using the alt-up (move lines up) shortcut in eclipse 3.4; I saw that this combination is actually a predefined shortcut for "Up" under:

System Settings -> Keyboard & Mouse -> Standard Keyboard Shortcuts

I've set "Up" shortcut to "None" and restarted eclipse (and the whole KDE - just in case), but eclipse is still not reacting to the shortcut.
xev for alt-up show two strange (as in "I don't know where they come from")  grab/ungrab events:

KeyPress event, serial 34, synthetic NO, window 0x3000001,
    root 0x7e, subw 0x0, time 18986320, (40,-12), root:(1015,13),
    state 0x0, keycode 64 (keysym 0xffe9, Alt_L), same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

    state 0x8, keycode 64 (keysym 0xffe9, Alt_L), same_screen YES,
    XLookupString gives 0 bytes:
    XFilterEvent returns: False

for comparison alt-down (which works as expected):

KeyPress event, serial 34, synthetic NO, window 0x3000001,
    root 0x7e, subw 0x0, time 19103897, (-705,574), root:(270,599),
    state 0x0, keycode 64 (keysym 0xffe9, Alt_L), same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

    root 0x7e, subw 0x0, time 19104020, (-705,574), root:(270,599),
    state 0x8, keycode 116 (keysym 0xff54, Down), same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

KeyRelease event, serial 34, synthetic NO, window 0x3000001,
    root 0x7e, subw 0x0, time 19104084, (-705,574), root:(270,599),
    state 0x8, keycode 116 (keysym 0xff54, Down), same_screen YES,
    XLookupString gives 0 bytes:
    XFilterEvent returns: False

KeyRelease event, serial 34, synthetic NO, window 0x3000001,
    root 0x7e, subw 0x0, time 19104177, (-705,574), root:(270,599),
    state 0x8, keycode 64 (keysym 0xffe9, Alt_L), same_screen YES,
    XLookupString gives 0 bytes:
    XFilterEvent returns: False

Is it possible that somehow the shortcut hasn't been unset?
