Bug#783865: [libglib2.0-0] xfgdesktop4 4.10.2-3 segfaults in g_slice_alloc () from libglib-2.0.so.0

[H.W.]

Package: libglib2.0-0
Version: 2.42.1-1
Severity: normal

--- Please enter the report below this line. ---

xfdesktop4 (4.10.2-3) segfaults in g_slice_alloc () from 
libglib-2.0.so.0. - xfdesktop is getting restarted by xfce's session 
management.
Once in a while restart is not succesful rendering the desktop 
non-usable i.e. no desktop icons, etc. There is no special interaction 
needed to trigger this segfault. Idle system produces segfaults 
periodically.

messages log:
