• create a preconfigured algorithm, and save it
• try open it
• see messages below

tagging as severe as is a new feature not working as expected.

It seems like this is the case only after adding the first preconf algorithm, it also breaks the original geoalgorithm. After restart of QGIS things seem to work fine again...
