Is this happening everytime you unplug? If so, could you execute in a terminal "solid-hardware listen", and unplug? Provide the output from that pls. Thanks !
Yes it's happening every time at the moment: <code> $ solid-hardware listen Listening to add/remove events: Solid::Backends::UDev::input_str_to_bitmask can't handle some bits ("4837fff", "72ff32d", "bf544446", "0", "0", "ffff0001", "30f90", "8b17c007", "ffff7bfa", "d9415fff", "febeffdf", "ffefffff", "ffffffff", "fffffffe") Segmentation fault </code>

Created attachment 81952 [details] New crash information added by DrKonqi knotify4 (4.0) on KDE Platform 4.11.00 using Qt 4.8.4 - What I was doing when the application crashed: happened several times when unplugging usb keyboard. my keyboard is a mac one, although this should not matter. I dont think this was happening in 4.10, could be new to 4.11 but I could be wrong. there could be some other external caused. I'm running Kubuntu 13.04 -- Backtrace (Reduced): #7 ~QString (this=0x7fff1501d030, __in_chrg=<optimized out>) at ../../include/QtCore/../../src/corelib/tools/qstring.h:880 #8 v_clear<QString> (d=0x7fff1501d030) at ../../include/QtCore/private/../../../src/corelib/kernel/qvariant_p.h:144 #9 clear (d=0x7fff1501d030) at kernel/qvariant.cpp:201 #10 0x00007f17e0d0697a in Solid::Backends::UDev::UDevManager::Private::isPowerBubtton (this=<optimized out>, device=...) at ../../../solid/solid/backends/udev/udevmanager.cpp:152 #11 0x00007f17e0d06bf2 in Solid::Backends::UDev::UDevManager::Private::checkOfInterest (this=0x280fec0, device=...) at ../../../solid/solid/backends/udev/udevmanager.cpp:121
