Status changed to 'Confirmed' because the bug affects multiple users.

This bug occurs when using the "SaveFile" desktop portal API and the user chooses a new file name rather than overwriting an existing file.

It can easily be reproduced with the following steps:

1. install the test-snapd-portal-client snap:

    snap install --edge test-snapd-portal-client

2. run the save-file test:

    test-snapd-portal-client save-file "foo"

3. in the file chooser, select a file name that does not exist.

The command will fail with a ConnectionAbortedError exception, and xdg-document-portal will crash with the following in the log:

    Jan 07 17:38:06 scruffy xdg-document-portal[30685]: error: Invalid id snap.test-snapd-portal-client: Names must contain at least 2 periods
    Jan 07 17:38:06 scruffy xdg-document-portal[30685]: error: **
    Jan 07 17:38:06 scruffy xdg-document-portal[30685]: xdg-desktop-portal:ERROR:document-portal/document-portal-fuse.c:206:xdp_inode_destroy: assertion failed: (inode->dir_fd == -1)

The problem does not occur with xdg-desktop-portal 1.0.3, so it is likely that one of the patches alexl mentioned at https://bugs.launchpad.net/ubuntu/+source/xdg-desktop-portal/+bug/1691649/comments/10 would fix it. With that said, backporting 1.0.3 might be the better option if we want working portals.
