Double-click on an attatchment or "Open" in the context-menu of an attatchment shows the file save dialog. The issue occurs with mails in the inbox. When opening a pdf attatchment from the mail-write window it doesn't do anything on double click or context menu -> open

I've tested opening an ".mp3" file from an attatchment and it worked. Opening pdf files from the file manager also works.

In the Attatchment settings the default open action is set to "Adobe Acrobat Reader" and can't be changed.

Deleting "mimeTypes.rdf" didn't change anything, but deleting the pdf entry in Settings->Attatchment solved the issue. This solution was proposed in Attachments won't open - permanently defaulted to save attachments
