Authentication failing when fetching from Bitbucket

[Alan Bowman]

I have a repository that I have had cloned for some time, and "git fetch" has worked perfectly (from the terminal started from the Sourcetree menu).  Up until recently, when I call it and it pops up the credential manager window.  When I enter the details, I then get the following error:

$ git fetch
Fetching submodule DUT
fatal: ArgumentOutOfRangeException encountered.
Specified argument was out of the range of valid values.
Parameter name: resultType
fatal: ArgumentOutOfRangeException encountered.
Specified argument was out of the range of valid values.
Parameter name: resultType
bash: /dev/tty: No such device or address

Git then appears to lock up, requiring a Ctrl+C to return to the command line.  I am using the latest embedded Git, version git version 2.17.1.windows.2.

Answer seems to be to use system Git with an upgraded version of the credential manager.
