In rename dialog for single file, typing extended characters with dead keys does not work. For example, in Spanish keyboard ['+a] -> "á" but in dialog line appears "a". Single key characters work OK: "ñ", "Ñ", .... (OS: Debian Testing).
We seem to have a user in Fedora seeing this now with 1.4.0. ;( It seems to be locale related somehow. It works in en_US.UTF8, but fails in pt_BR.UTF-8. Downstream report: https://bugzilla.redhat.com/show_bug.cgi?id=838193 Happy to pass along any ideas for debugging or fixes.
From the downstream bug: "I think I found the problem. It turns out that when I remove the line <property name="IMPreeditStyle" type="string" value=""/> from ~/.config/xfce4-old/xfconf/xfce-perchannel-xml/xsettings.xml everything works!"
Fixed in adf990f. We don't set any of the IM properties.
