Hi, I just wanted to read the story linked above and the XFCE panel crashed. Turns out there are two unicode line seperator characters (<U+2028><U+2028>) in the pages title tag. I then saved the page to my desktop for further investigation and the desktop crashed too. XFWM seems unaffected and actually seems to display the line breaks (see attached screenshot). I ran xfce4-panel with strace and this is what it displayed multiple times before segfaulting: read(3, "\1\1%\10\0\0\0\0\375\257\200\0\0\0\0\0\0\0\0\0\0\0\0\0\20\365\34\n\0\0\0\0"..., 4096) = 32 read(3, 0x8ce47ec, 4096) = -1 EAGAIN (Resource temporarily unavailable) select(4, [3], [3], NULL, NULL) = 1 (out [3]) writev(3, [{"+\0\1\0"..., 4}], 1) = 4 select(4, [3], [], NULL, NULL) = 1 (in [3]) read(3, "\1\2&\10\0\0\0\0B\0\340\1\0\0\0\0\1\0\0\0\0\0\0\0\20\365\34\n\0\0\0\0"..., 4096) = 32 read(3, 0x8ce47ec, 4096) = -1 EAGAIN (Resource temporarily unavailable) select(4, [3], [3], NULL, NULL) = 1 (out [3]) writev(3, [{"(\0\4\0\33\0\340\0;\1\0\0\0\0\0\0"..., 16}], 1) = 16 select(4, [3], [], NULL, NULL) = 1 (in [3]) read(3, "\1\1'\10\0\0\0\0\375\257\200\0\0\0\0\0\0\0\0\0\0\0\0\0\20\365\34\n\0\0\0\0"..., 4096) = 32 read(3, 0x8ce47ec, 4096) = -1 EAGAIN (Resource temporarily unavailabl Reproducible: Always Steps to Reproduce:
