Upgrade to 4.1.2 freezes after file transfer, forced shutdown required

[KevinKidd]

Hello, Two of our staff have upgraded from 4.0.2 to the new version of 4.1.2, with the same results. After installation everything seems fine, but after the file is transferred to the server via SFTP, the beach ball appears and Cyberduck becomes unresponsive forcing a manual force quit. Upon relaunch of the program everything seem fine until you transfer a file again and the same occurrence happens again. Our staff members, who upgrade, have trashed the new version and have gone back to using 4.0.2, so I have no log drawer information.

Here is some information about our machines:

Please let me know if you need additional information to help track down this issues.

Duplicate for #6183. As a workaround, disable the option Transfers → Remove when transfer completes in Preferences or upgrade to the latest snapshot build available.
