Package: libqtcore4
Version: 4:4.8.5+git242-g0315971+dfsg-2
Severity: normal
File: qt4

Dear Maintainer,

I was trying to assign MicMute key in KDE system settings, but when I press it I get output window 'The key you just pressed is not supported by Qt'.

Here is xev output for the key:

KeyPress event, serial 43, synthetic NO, window 0x7a00001,
    root 0xa4, subw 0x0, time 1008043, (162,-14), root:(162,9),
    state 0x0, keycode 198 (keysym 0x1008ffb2, XF86AudioMicMute), same_screen YES,
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

KeyRelease event, serial 43, synthetic NO, window 0x7a00001,
    root 0xa4, subw 0x0, time 1008043, (162,-14), root:(162,9),
    state 0x0, keycode 198 (keysym 0x1008ffb2, XF86AudioMicMute), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

I am running Lenovo X230 laptop if this matters.
