Locking assertion failure libxcb-xlib.so.0 xcb_xlib_unlock

[LimCore]

While using recordmydesktop and switching windows with alt-tab I get errors like
"Locking assertion failure"
in
#0 /usr/lib/libxcb-xlib.so.0 [0x7f1caa44997c]
#1 /usr/lib/libxcb-xlib.so.0(xcb_xlib_unlock+0x24) [0x7f1caa449a84]
#2 /usr/lib/libX11.so.6 [0x7f1cacc18260]
#3 /usr/lib/libX11.so.6(XNextEvent+0x62) [0x7f1cacc00c12]

#5 /lib/libpthread.so.0 [0x7f1cac0b63f7]
#6 /lib/libc.so.6(clone+0x6d) [0x7f1caa721b2d]

The resulting file seems to be rather ok (but quality is bad in the moments when the above error happens - movie lags for 1-2 seconds).

Dualcore amd64 ubuntu 8.04 up to date, nvidia binary driver (glx-new)

After a moment program freezes up totally, ctrl-C doesn't work.
I do ctrl-z but then I can not strace or gdb that process:

Can confirm on an i945. Probably has to do with xorg updates not too long ago.

[Sarah Kowalik (hobbsee-deactivatedaccount)]

fixed in intrepid version - needs a backport.

[Stephan Rügamer (sruegamer)]

I would like to know if you started recordmydesktop with the "-channels 2" switch?
I can confirm those crashes, when trying to record the desktop and trying to record even sound in stereo.

I backported for me the intrepid version, and it behaves the same.

Ubuntu Feisty Fawn is no longer supported, so a SRU will not be issued for this release. Marking Feisty as Won't Fix.

[Chucky (lechuck)]

Problem still present in Ubuntu 8.04.1 LTS with latest updates on 2009-01-13.

I can confirm this is not directly related to recordmydesktop, to the "-channel 2" option shouldn't have any impact. It occurs in other situations such as when running a Java application relying on the AWT.

This is a bug is in the lib.

[Maximiliano Fragale (fragale)]

El problema se ocasiona con los efectos de escritorio, evidentemente la biblioteca contiene un bug como dice Chucky "This is a bug is in the lib", especificamente en la libx11-6.
Para solucionar este problema probar arrancando desde la linea de comandos con la opcion --full-shots

ej.

maxi@sony:~$ recordmydesktop --full-shots

en el entorno de gtk-recordMyDesktop, entrar en avanzado y seleccionar "Capturas completas en cada cuadro"=Habilitado

Es todo, con eso funcionara.

ahora va la traduccion de google al inlges.

The problem is caused by the effects of a desk, obviously the library contains a bug like Chucky says "This is a bug is in the lib," specifically in libx11-6.
To solve this problem try booting from the command line with option - full-shots

ej.

maxi @ sony: ~ $ recordmydesktop - full-shots

around the gtk-recordMyDesktop, enter into advanced and select "Capture Complete each table" = Enabled

That's all, that worked.
