rclone: Single backslash character in path stops the sync

What is the problem you are having with rclone?

Syncing a large directory got stuck on certain files. I found out the directory name contained: the following string: path with spaces\something. The \s was causing errors.

What is your rclone version (output from rclone version)

rclone v1.43.1
- os/arch: linux/arm
- go version: go1.11

Which OS you are using and how many bits (eg Windows 7, 64 bit)

Linux 4.14.73-1-ARCH #1 SMP PREEMPT Tue Oct 2 00:44:19 UTC 2018 armv7l GNU/Linux

Which cloud storage system are you using? (eg Google Drive)

Webdav/ OwnCloud + crypt overlay

The command you were trying to run (eg rclone copy /tmp remote:tmp)

rclone sync localDir secret:/target --progress --checksum

A log from the command with the -vv flag (eg output from rclone -vv copy /tmp remote:tmp)

looking up through the debug outputs, the plist and wflow files aren’t printed even? or maybe too long ago (as there are many files being checked)

Workaround

--exclude "**\\\\**"
