File transfer stuck midway during transfer

[pcvvelzen]

Describe the bug, Current Behavior and Context
When transferring files from my Mac to Android device (Xiaomi Note 6 Pro), OpenMTP gets stuck on transferring one specific file. This happens again after second attempt and seems to be related to some corruption within certain backed-up files.

The application interface is still usable but there is no way to skip to next file, or to cancel the transfer as a whole.

Expected behavior and Possible Solution
Because OpenMTP of course cannot guarantee the validity and reliability of the content being transferred through the app. A timeout of X seconds after being stuck on transferring one file would be expected, or a prompt which allows the user to skip file or cancel the whole transfer.

Steps to Reproduce (for bugs)
Unfortunately the issue appears to be hard to replicate and a combination of some corruption in data and external harddisk used.

• Setup a symlink to a directory with a couple of dummy files
• Start transfer from the symlink source destination machine to Android device through OpenMTP
• Midway during transfer remove the symlink target

Your Environment
Include as many relevant details about the environment you experienced the bug in

• Node version : v12.17.0
• Version or Branch used : stable
• Operating System and version Catalina 10.15.6
• App Version OpenMTP-v2.4.4

Attachments
Unfortunately the directory with logs didn't contain any content:

symlinks are tricky. In the next release of OpenMTP this issue should be fixed (at least temporarily)

This should have been fixed by #181

Keeping this open until the stable release it out.

Could you download the latest community beta version of OpenMTP from https://drive.google.com/file/d/1wpSlkGWZKe4-nRYcdJaPVA3Y6kOBMTsO/view?usp=sharing and let me know whether your device is recognized?
