Нашёл что-то похожее: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=756770 Наконец дошло, что это Segfault. Запустил через gdb и получил: Program received signal SIGSEGV, Segmentation fault. 0x0000003da1680c03 in _g_utf8_normalize_wc (str=0x0, max_len=max_len@entry=-1, mode=mode@entry=G_NORMALIZE_ALL) at

из-за какого-то левого desktop-файла. Я даже нашёл его и прикладываю. Завёл багу в апстриме https://bugzilla.xfce.org/show_bug.cgi?id=14655 |
