I have an attachment called 'Gründung.pdf' added to KMail. Result: The attachment is renamed to 'application-pdf-attachment' (all other attachments keep their name!) Windoze-user complain 'they cant open the attachement' although the content seems to be OK
Could you provide a screenshot about "renaming" ? it's in viewer ? in composerview ? etc.
Actually I cant reproduce it at the moment - but there was an update to some libQT and libKF5 libraries installed yesterday. I will send an update once I can reproduce. Thanks Axel
If you can provide the information requested in comment #1, please add it.
Wait for new info
I cant reproduce it in current 5.5.1, therefore closing. Thanks for looking into this!
