Problem Description

The expected extension of the file is unclear if i try to load or save a profiling result.
This could be improved by providing better information, saving the file with extension if no extension was given and/or allowing to select "any file extension" in the save dialog.

This error was found on Gnome and its one of many filedialog integration things, but maybe this can be improved in the future :)

What steps reproduce the problem?

1. Save Profile/Load Profile
2. See that there is no file extension in the save dialog

What is the expected output? What do you see instead?

Hi @maurerle thank you for the feedback! Could this be related with #18684 ? And if so, maybe a similar approach as in #17790 could be implemented for this?
