Version: 2.0.2 (using 4.2.2 (KDE 4.2.2), Kubuntu packages) Compiler: cc OS: Linux (i686) release 2.6.27-11-generic The default global shortcut for increase volume doesn't work for me. Everything else looks fine, Meta+- (decrease volume) and Meta+M (mute) work. The app shortcut + e - work fine too. I'm using a brazilian ABNT2 keyboard.
Sorry, I can't reproduce this with KDE 4.2.2 and Amarok SVN trunk (2.1). The "Meta++" shortcut (which admittedly looks a bit weird) works OK here. However, please keep in mind that this doesn't work with the "+" key on the number block, but only with the one on the main alphanumeric block. Whatever the problem is, it's probably not an Amarok bug, but on a lower level (KDE or Qt).
Why shouldn't the '+' in the number block work? It worked fine in Amarok 1.4, and it works in other apps like Firefox (I've not tested other Qt/KDE though). This is important because in brazilian keyboards, the main '+' key is actually shift+=, so it doesn't work in any shortcut.
I'm reopening this bug for 3 reasons. First, as I said, this is important for non-US keyboards. Second, it worked fine on 1.4. Third, it works on Konqueror 4.2.2
As Mark already said, this is *not* a problem in Amarok, but more likely a KDE or a Qt issue. Please open a new bug upstream for kdelibs.
I opened http://bugs.kde.org/show_bug.cgi?id=212386 for this. I hope the KDE team will fix it or pass it upstream to Qt.
