[Pkg-xfce-devel] Bug#550533: Reloading xmodmap freezes system with high load between xfwm4 and dbus

[Robert]

Package: xfwm4
Version: 4.6.1-1
Severity: normal

When loading a lot of keysymbols with xmodmap the system freezes for about 1 Minutes, with high CPU load on xfwm4 and dbus.

This behaviour started occuring after upgrading xfce4 from 4.4 (stable) to 4.6 (testing), before loading a complete keymap took fractions of seconds.

During the mere reload of the keymap the dbus-monitor records 41MB of DBUS-Messages generated from xfwm4.


Reproduce:
1. Save your xmodmap (or take any other):  xmodmap -pke > xmap
2. Reload the settings: xmodmap xmap
