Ah, I see, what you mean is that *the current working directory* is
appended. (Which in your example is $HOME, which confused me, since
replacing ~ with $HOME is expected.)
Yeah... well, the bad news is that tilde expansion (not unlike variable
expansion) is usually a shell function and/or needs to be invoked
manually, rather than an OS function. It appears that QFileDialog also
does the expansion, but if your path comes from another source, I guess
