[SOLVED] XFCE keyboard shortcuts don't work anymore [-current]

kaapa · 03-16-2011, 06:18 AM

I'm using -current (xfce-4.6.2)

I've noticed that the shortcuts I define aren't working anymore. The ones I define through windowmanager -> keyboard are ok, but the ones through keyboard-> application shortcuts are ignored.

Anyone saw this behavior?

Thanks

Found the reason, just don't know what's causing this

probably xfce should be recompiled with the new glib2 ??

kaapa · 03-16-2011, 08:00 AM

But this is --current, I wouldn't expect to have problems with it

Some issues in .config/xfce4/xfconf/xfce-perchannel-xml . Moved them out of the way and after restart xfce worked again

I've just hit this bug today. In case this is of help to anyone, the problem is an invalid free in xfce4-settings-helper/pointers.c. The commit which fixes this is commit 92b0b61cf7cd82861d8a7ff407b0b2b927b4151f in the xfce4-settings git repository.

Code:

commit 92b0b61cf7cd82861d8a7ff407b0b2b927b4151f
Author: Nick Schermer <nick@xfce.org>
Date:   Thu Dec 2 18:55:48 2010 +0100

    Fix free of invalid memory (bug #6909).
