OpenGl app crashes with "No buffer for z buffer"

I am the current maintainer of a java application that uses OpenGL via the JOGL bindings (http://sourceforge.net/projects/fgflightplanner). This app crashes with the following message in the console when using the latest Radeon driver under Fedora 12:
drmRadeonCmdBuffer: -22. Kernel failed to parse or rejected command stream. See dmesg for more info.
dmesg has the following 2 entries:
[drm:r100_cs_track_check] *ERROR* [drm] No buffer for z buffer !
[drm:radeon_cs_ioctl] *ERROR* Invalid command stream !
If I boot with radeon.modeset=0, the application runs (but not well, always on top of everything)
The application is a mature app and runs well with other drivers (fglrx) and on other platforms.
I am using Fedora 12 with all the latest updates:
$ uname -a
Linux kelpie5.campbell.priv 126.96.36.199-174.fc12.i686 #1 SMP Mon Dec 21 06:24:20 UTC 2009 i686 i686 i386 GNU/Linux
This is an issue in the Mesa driver or in the kernel, not in the X driver.
probably same as bug 23532.
