I'm on Thunar 4.18.3. I can trigger the bug by opening a directory in Thunar and adding and removing files for a while, the crash then happens when trying to open or rename a file. ``` Thread 1 "thunar" received signal SIGSEGV, Segmentation fault. thunar_file_get_display_name (file=file@entry=0x0) at thunar-file.c:3303 3303 return file->display_name;
