Comment 14 for bug 487997

Thanks Floki. It looks that the Compose file is being read properly and the problem should be something else.

Another direction to investigate if the problem has to do with character encodings. A bug reported a few times with KDE apps in Ubuntu is that when you try the Open dialog box and attempt to open a filename with Unicode characters (non-ISO-8859-1), the program fails. I think it shows the characters as ???????

So, you can create a file with name ΑυτήΕίναιΜιαΔοκιμή.txt, then try to view/open it with the File/Open option. If you see ?????? characters instead of Unicode, and you have the deadkey issue, then it might be a more general problem.

Apart from that, I cannot think of a possible problem. You would need to take it to the KDE and QT teams.
