crashes in the nvidia blob but this: #11 0x00007f3a7d16afe4 in KWin::GLShader::setUniform (this=<value optimized out>, location=5, value=<value optimized out>) doesn't rule out a nullpointer access ("this=<value optimized out>") like in bug #283577 since there's a known bug in the cube/slide effects, you should disable those until 4.7.3 (see bug #280455)
*** Bug 287843 has been marked as a duplicate of this bug. ***
let's assume it's either a driver issue or the cube issue which is already fixed. If it is still reproducable we would need a gdb log directly with a breakpoint at the right location. Not nice to do in case of KWin, I have to admit.
