Webmin 1.973 Just updated from 1.890
Attempt to upload several files produces following error in the file progress popup before any transfer:

HTTP/1.0 500 Perl execution failed
Server: MiniServ/1.973
Date: Fri, 30 Apr 2021 23:53:55 GMT
Content-type: text/html; Charset=utf-8
Connection: close
Error — Perl execution failed
Illegal division by zero at /usr/share/webmin/uptracker.cgi line 87.

This is repeatable.

I have narrowed it down to if any file in the list of files is a named pipe file then this happens. It does not matter where in the list this file is.

Does this also happen if one of the uploaded files is zero bytes long?

let me check!

When one tries to upload a 0 length "normal" files the pop up pops and
appears to work...
Except the Upload page resorts the status of:
Failed to upload files : No files selected to upload!

which is completely different.
In this case I would say this is a bug too! One should be able to upload 0
length regular file.

thanks

Ok, I see the bug that causes this - it will be fixed in the next Webmin release (1.975)
