How to reproduce: 1. create some text file and save it without suffix - make sure OS doesn't hide suffixes making you think that there is no suffix in a filename 2. Open query editor window 3. Select File / Open... 4. Enter star character (*) into filename field and commit it hitting enter - in result you will get all files listed in file browser 5. find your file 6. select it and open it - this operation will end up with error: "can't open file"
