Division by Zero

I did copy a php-file via sftp from local to a remote system.
After succesful copying the file, I got the error 'division by zero' in a standard message box.

WinSCP 5.5.4 (Build 4433). Installed via PortableApps.

Windows 7/64Bit (Build7601: SP1) german

Command GUI

The program did still worked fine after that.

I have to add: the error was not repeatable.

Thanks for your report. Please let us know if you find a way to reproduce the bug.
