User Feedback

I was trying to 'save as' a .shp polygon vector as a MapInfo TAB file with symbology exported as 'Feature Symbology'... then it crashed.
It also crashed when exporting symbology as 'Symbol layer symbology'
It DID NOT crash when saving as a TAB file without symbology export selected.

This crash appears to be related to the symbology export, regardless of file type being export. If anything other than 'no symbology' is selected, QGIS 3.0.0 will crash.
