Nautilus crashes with an "assertion error" whenever accessing a folder, which is a symbolic link to a folder in another filesystem, and then deleting any file inside that folder (the file is not deleted).

Steps I used to reproduce de problem in my machine:

1) /dev/sda1 partition mounted on root folder with XFS filesystem;
2) /dev/sda2 partition mounted on /mnt/data folder partition with EXT4 filesystem;
3) create a folder "/mnt/data/test" and the empty text file "/mnt/data/test/file.txt";
4) in your home folder, create a symbolic to the "test" folder above with "ln -s /mnt/data/test";
5) open the symbolic link folder with "nautilus <home_folder>/test";
6) delete the "file.txt" file (pressing the delete button) and watch nautilus crashing with the following error:

nautilus: malloc.c:2909: __libc_malloc: Assertion `!victim || ((((mchunkptr)((char*)(victim) - 2*(sizeof(size_t)))))->size & 0x2) || ar_ptr == (((((mchunkptr)((char*)(victim) - 2*(sizeof(size_t)))))->size & 0x4) ? ((heap_info *) ((unsigned long) (((mchunkptr)((char*)(victim) - 2*(sizeof(size_t))))) & ~((2 * (4 * 1024 * 1024 * sizeof(long))) - 1)))->ar_ptr : &main_arena)' failed.
