Hello Md Ayquassar,
sorry, I did not recognize that you
seem to have a usrmerge'd system.
Then I get following backtraces from your
core dump, with and without debug symbols.
It looks like a function pointer gets called
unconditionally, while containing NULL.
Seems to be graphics driver related.
Kind regards,
Bernhard
