assert triggered during propagation, potentially due to network error

[buhtz]

I have no idea what is going on here. The server is not mine.
The "userdata-mlu" is a "fileserver" connected via SMB to my owncloud account.

What can I do? The client runs on Debian stable.

Thanks for the report! It's possible that there are two issues here: The ASSERT is definitely a client bug, it's possible it gets triggered by another issue relating to the SMB external storage on the server.

@noMICROSOFTbuhtz You're using an old client, before 2.5.1. Which version was this exactly? Can you reproduce the issue? If so, please try with 2.5.4. The code handling "Server does not support X-OC-MTime" has been changed.

This bug was likely fixed for 2.5.0 by 3f4d504 see #6403.
