Changing character case when renaming doesn't persist

[Waldo]

Ubuntu 19.10
nautilus version: 1:3.34.1-1ubuntu1

Upon pressing F2 to rename a file, if delete one of the characters and replace it with the same character, but a different case, and you click rename, the changes should save.
Instead they get discarded

E.g. renaming foo.c -> Foo.c keeps it as foo.c instead of renaming it to Foo.c

Thank you for your bug report. On what disk/filesystem are you doing the change? Some filesystems like vfat are not case sensitive which leads to such behaviours... on a normal ext linux partition the case is correctly preserved on my installation

[Waldo (glibg10b)]

Linux is install on an ext4 partition, where the files are also located. I suspect this is nautilus-specific. mv foo Foo yields the correct results
