Do you have the possibility to provide an example RAW that was shot in portrait mode? The only example RAW that we have available is shot in landscape, so I currently have no possibility to reproduce the issue.
When zooming in on the photo, the meta data (ISO, aperture and shutter speed) is not shown correctly. They all show up as 0. Note that correct values are shown on the side panel.
I haven’t been able to reproduce this, but this might be caused by wrongly cached metadata, which could be the consequence of an earlier crash during import/scanning (shouldn’t happen anymore). The metadata pane on the right uses the cached data only for a quick preview and then ultimately reads the actual metadata from the file, whereas the details view relies solely on the metadata cache.

There actually is code in place to remove black bars from RAW thumbnails, because those are pretty common, but for some reason this fails here. The more serious part is that it shouldn’t fall back to the thumbnail at all here, if anything it should fall back to the the full developed version, like mentioned above, or display nothing at all. I’ll look into this.
