Export png fails with: Invalid cross-device link

[Heinrich Schuchardt]

Export png fails with "Invalid cross-device link" if /tmp is mount as tmpfs.

I have stored https://assets.ubuntu.com/v1/ce518a18-CoF-2022_solid+O.svg as file /home/user/CoF-2022_solid+O.svg.
I open inkscape on the command line with inkscape CoF-2022_solid+O.svg.
I select export png and try to export to my home directory.
A file of length 0 is created.
The console shows an error message:
"boost::filesystem::copy_file: Invalid cross-device link: "/tmp/ink_ext_CF77T1", "/home/user/temp/cof.png"

The following mounts exist:

/dev/mapper/vgkubuntu-home on /home type ext4 (rw,relatime)
zfsdt@workstation5:~/temp$ mount | grep '\/tmp'
tmpfs on /tmp type tmpfs (rw,relatime,inode64)

So /tmp and /home are actually separate devices.

ln -s /home/user/temp/cof.png /tmp/cof.png
works fine.

ln /home/user/temp/cof.png /tmp/cof.png
fails with
ln: failed to create hard link '/tmp/cof.png' => '/home/user/temp/cof.png': Invalid cross-device link

Exporting to /tmp works.

Inkscape should not create hardlinks on /tmp as /tmp typically is a tmpfs.

Inkscape 1.3-dev (1:1.2.0-alpha1+devel+202210180739+994e1ec499) from ppa:inkscape.dev/trunk works fine. We should update the package.

Debian has 1.2.1+ds-1 in sid.

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

Could this be related to a recent break of syscall copy_file_range.

[Torbjörn Rathsman (milasudril)]

Problem appears to be fixed in Inkscape 1.2.2 (1:1.2.2+202212051552+b0a8486541). Please update the official package ASAP.
