Does the appended patch fixes the problem?

Best regards, Michael.

As filling the disk is tedious, I have to make different system for
testing like making a loop device and mounting user directory
there. Then I can try again. It may take some days.

LGTM, thanks.

Just curious: why the shorter timeout, and why so short (from 25s to
1s)?

Thanks for the feedback.

If the D-Bus call doesn't get any response, it would block Emacs for
that time (25 seconds). And my experience is, that D-Bus is much more
responsive than 1 second, if everything goes normal.

@Jean: I'm closing the bug, because I believe it fixes the issue. If you
find that it doesn't, pls reopen.

Best regards, Michael.
