Possible bug in 'backup.cgi' after these commits!?

Hi,

I don't know if this will become relevant, but...

I tested these two commits:

https://git.ipfire.org/?p=ipfire-2.x.git;a=commitdiff;h=7f6257e0a475681ff243...

and

https://git.ipfire.org/?p=ipfire-2.x.git;a=commitdiff;h=614764e58af6dd710658...

Keen to experiment (as I am), I installed the new 'backup.cgi' on my running Core 123.

After this, GUI looked normal. I could still make backups. But I couldn't delete the addon backup files. After clicking on the 'delete' icon, GUI disappered, came back partially (as it seemed, only the header) and after hitting 'reload', the addon backup files (*.ipf) were still there. IPF-file rights seemed to be ok, but I couldn't delete them through the GUI.

Can anyone confirm? Or is it my mistake?

Best, Matthias
