Thank you! It proves that this is a bug either in libX11 or in python. Reassigning from gnome-abrt to libX11. I've run gdb on the core file: #0 XCloseDisplay (dpy=0x73e77c0) at ClDisplay.c:51 #1 0x00000080f8a8804c in 00000010.plt_call.strchr@@GLIBC_2.3+0 () from /lib64/libffi.so.6 #2 0x00000080f8a87778 in .ffi_call () from /lib64/libffi.so.6 #3 0x00001ffff953adb4 in ._ctypes_callproc () from /usr/lib64/python2.7/lib-dynload/_ctypes.so #4 0x00001ffff952d884 in 00000010.plt_call.PyCData_AtAddress+0 () from /usr/lib64/python2.7/lib-dynload/_ctypes.so #5 0x00000080f8de4554 in .PyObject_Call () from /lib64/libpython2.7.so.1.0 #6 0x00000080f8ee5a6c in .PyEval_EvalFrameEx () from /lib64/libpython2.7.so.1.0 #7 0x00000080f8eec814 in .PyEval_EvalCodeEx () from /lib64/libpython2.7.so.1.0 #8 0x00000080f8eec92c in .PyEval_EvalCode () from /lib64/libpython2.7.so.1.0 #9 0x00000080f8f255cc in .PyRun_InteractiveOneFlags () from /lib64/libpython2.7.so.1.0 #10 0x00000080f8f259b0 in .PyRun_InteractiveLoopFlags () from /lib64/libpython2.7.so.1.0 #11 0x00000080f8f26328 in .PyRun_AnyFileExFlags () from /lib64/libpython2.7.so.1.0 #12 0x00000080f8f41a04 in .Py_Main () from /lib64/libpython2.7.so.1.0 #13 0x0000000010000720 in .main () wfm on F20. |
