I/O error spamming when no free disk space

[goto1134]

qBittorrent version and Operating System

Windows 10 Pro version 1709 build 16299.64
qBittorrent version 4.0.1 (64-bit)

What is the problem

If there is I/O error that lasts for some time (in my case, it is that my disc filled), numerous I/O error popups appear. They are really annoying and coutinue to appear while the problem is still present.

What is the expected behavior

I would like to have one popup notification. In case of different kind of problems there can be more than one notifications. In case of the problem remains and notification is closed, it can be repeated, I think

Steps to reproduce

1. fill the disk
2. start downloading any torrent to the disk

This issue has been closed and locked for being too old, and thus either most likely resolved in recent versions or no longer applicable.
If you experience the reported problem or similar in the latest version, please open a new issue report with the requested information in the issue template.

A new issue report with relevant updated data gathered from the latest version is preferable to necroing an old report with a comment like "still happens in version x.y.z", even if you think the bug is the same, or suspect of a regression.
Due to the changes made to the qBittorrent code and its dependencies over time, the exact cause of your problem could be totally different than the original one, despite the visible symptoms of the bug being similar.
Thus, providing relevant updated information is crucial to find and fix the root cause of a recurrent problem or regression.

Thank you for your contributions.
