Description
Issue Summary
For a repository where diff transcoding is enabled, subsequent attempts to save repository settings fail with an error indicating "Diff transcoding could not be enabled. Check the logs for more details."
Steps to Reproduce
- Enable diff transcoding. The first enable should work
- Try to save repository settings a second time with diff transcoding still enabled
Expected Results
Repository settings should save without errors. Since diff transcoding was already enabled, it should remain enabled.
Actual Results
Repository settings are not saved, and an error is shown.
An exception similar to the following is shown in the log files:

Workaround
Disable diff transcoding and save settings. Then reenable transcoding and save again.
