Package: gnome-settings-daemon
Version: 2.30.2-3
Severity: grave

The daemon segmentation fault on loading the plugins of
/usr/lib/gnome-settings-daemon-2.0/*.so. The log of running
"gnome-settings-daemon --no-daemon --debug" is attached.

Please note that it segfaults on any *.so loading, not just
libxrandr.so, which is verified by disabling each *.so file that causes
the segfault. Also, the system is a Loongson2F based laptop running on
mipsel.

    GDB is unable to find the start of the function at 0x406d77
and thus can't determine the size of that function's stack frame.
This means that GDB may be unable to access that stack frame, or
the frames below it.
    This problem is most likely caused by an invalid program counter or
stack pointer.
    However, if you think GDB should simply search farther back
from 0x406d77 for code which looks like the beginning of a
function, you can increase the range of the search using the `set
heuristic-fence-post' command.
