I can't write on file `".Document.tex.aux"'.

[sm8ps]

Describe the bug Gummi works fine as long as the document is NOT saved. As soon as I save any document the build log show the following error line:

/home/user/temp/.Document.tex.swp:8: I can't write on file `".Document.tex.aux"'.

This does happen even with the sample document.

To Reproduce Steps to reproduce the behavior:

1. Start Gummi with the sample document in the editor panel and the preview is shown.
2. Save the document in the file system as 'Document.tex' and the preview does not work and the aforementioned error message about not being able to write on file `".Document.tex.aux"'. is shown.

System:

• Ubuntu 24.04 with KDE Plasma
• Gummi version 0.8.3 installed via Apt Notably this error does not happen with the Flatpak installed version 0.8.3. However, that one is not usable in my set-up because the icons are not properly showing, presumably because of some GTK vs. KDE issues.

Other I have seen #110 but none of the information there helped me work around or even solve the problem. This one see much more deeply rooted.
