sync behaving oddly

[duncdrum]

To reproduce

Install a .xar package modify it and then go to Application -> Synchronise

With a target directory on the local FS e.g /user/temp, no matter where the modification happend, a each collection gets also synced as an empty director

I can no longer get exide to do a full sync.
On a side note from inside docker sync doesn't work at all.

In both cases download Application -> Download app works as expected
