After update to the current F19, my keyboard layout switches back to US randomly. I have cs-qwerty layout as primary. When I'm typing, the layout changes back to US without reason. I have xfce4-xkb-plugin-0.5.5-1.fc19.x86_64, Xfce desktop.
If something happens randomly, there is not much I can do. If I cannot reproduce it, I cannot forward your bug to the upstream developers. So either you tell me how to reliably reproduce your bug or talk to the upstream developers directly by filing a bug in bugzilla.xfce.org.
Sorry. Better word is "after typing few sentences". I'll try to find some clues and post back later.
This bug already is filled in upstream bugzilla - look here: https://bugzilla.xfce.org/show_bug.cgi?id=10152 They say that it is fixed in the upstream version 0.5.6, so you can do some diff and see where to fix it in the downstream. I assume that it's common issue of 0.5.5, it's discussed also here: https://bbs.archlinux.org/viewtopic.php?pid=1280887 It happens to me too, the interval really is cca 10 minutes. After I manually downgraded the package back to version 0.5.4.3-2, everything seems OK.
