i tried to download a 2GB file from my gdrive with the latest rclone master (1.47-dev), after some seconds it crashes with a huge traceback(see above). This problem does not occur with 1.46-dev.
I used this mount command:
rclone mount gcache: /mnt/gdrive --no-modtime --vfs-cache-mode=full --allow-other --vfs-cache-max-size 10G --file-perms 775 --dir-perms 775 --umask 002 -vvvv
I followed the "build from source" instructions on nuetzlich.net, there is no choice between stable/dev - I now found the stable downloads - thanks alot! Problem gone!
