So-so synchronisation

[sl-lebrit]

Describe the bug
Sometimes synchronisation goes into long pauses during 'preparation' for downloading. Sometimes it resumes, sometimes the transfer stops. After a possible automatic restart of the download, the bug can be expected to recur.

To Reproduce
Steps to reproduce the behavior:

1. Open a bookmark
2. Select a folder in a Cyberduck, in this case the folder contains a hierarchy of folders with only small/medium size images inside (the total size is about 70GB and the images count is about 10'000
3. Select the menu command "Synchronize..." than a local folder and start synchronisation
4. The bug suddenly arise...

Expected behavior
Simply prepare and download all files without excessive pauses.

Log Files

Additional context
When the first synchronisation ends, many files are missing in the local folder and you have to synchronise again.
