--- Comment #4 from Dāvis <davispuh@gmail.com> ---
Got same crash, but for ksplashqml, using Qt 5.5 and plasma-workspace from git
master branch.

ksplashqml[2023]: Loading stage  "initial" 345

It's Qt bug, strstr is called with null pointer, look at

http://code.qt.io/cgit/qt/qtdeclarative.git/tree/src/quick/scenegraph/qsgcontext.cpp?h=5.5#n658

    const char *vendor = (const char *) funcs->glGetString(GL_VENDOR);
    if (strstr(vendor, "nouveau"))

funcs->glGetString() returns null pointer for some reason (Xorg/GPU driver
failed or something), but anyway Qt should just abort and quit.
