Bug 9195

Mostly while using konqueror (doesn't matter if browsing the web or local 
files), kombmgr exits with a failed assertion (with the two error lines coming 
some seconds or minutes before): 
 
kakra@ganymed ~ $ kompmgr 
trying '/home/kakra/.xcompmgrrc' as configfile 
 
 
finished parsing the config file 
Started 
error 3 request 20 minor 0 serial 3375176 
error 3 request 20 minor 0 serial 3385782 
kompmgr: xcb_io.c:178: process_responses: Assertion `!wait_for_first_event || 
dpy->head' failed. 
Abgebrochen

Recompiled kwin just to be sure kompmgr is rebuilt with XCB-enabled Xlib 
(gentoo packages), but the failure persists: 
 
kakra@ganymed ~ $ kompmgr 
trying '/home/kakra/.xcompmgrrc' as configfile 
 
 
finished parsing the config file 
Started 
error 3 request 20 minor 0 serial 7334486

dpy->head' failed.

Here's my config: 
 
kakra@ganymed ~ $ cat .xcompmgrrc 
[xcompmgr] 
Compmode=CompClientShadows 
DisableARGB=true 
FadeInStep=0.07 
FadeOutStep=0.04 
FadeTrans=false 
FadeWindows=false 
ShadowColor=0x000000 
ShadowOffsetX=0 
ShadowOffsetY=-80 
ShadowRadius=8

These failures also happen when using xcompmgr. Further, it seems to be 
sensible to the values used in the config. Some values make it fail with a 
segfault almost instantly after starting.

I first thought, it would be a KDE kompmgr bug. But the guys from bugs.kde.org 
pointed me here. I could reproduce this bahaviour with xcompmgr, so I reported 
it here. Original report: http://bugs.kde.org/show_bug.cgi?id=137908
