I can confirm this issue, we'll need to investigate this further.
The issue is in KIO. Working on a fix, thanks for reporting!
Git commit 233a00b7e162916bbe672fd9fac81e61dc1e14c5 by Elvis Angelaccio. Committed on 26/05/2018 at 16:36. Pushed by elvisangelaccio into branch 'master'. KFileItemActions: fallback to default mimetype when selecting only files Summary: KFileItemListProperties::mimeType() returns an empty string if the selected files have different types, but KMimeTypeTrader does not support empty mimetypes as query argument. This causes the following warning KMimeTypeTrader: mimeType "" not found and breaks the bluedevil's 'Send via Bluetooth' plugin. If we know the user selected only files, we can use the default mimetype as fallback. FIXED-IN: 5.47 Test Plan: Select two files with different extension and check 'Send via Bluetooth' is in the Dolphin context menu.
