Bug#463159: XCB-enabled libx11 causes hangs in various X clients
Package: libx11-6
Version: 2:1.1.3-1
Severity: critical
This is only 'critical' because it causes unrelated software (e.g., Side
Effects Software's Houdini) to break by causing hangs. Feel free to
downgrade, but this is a very important bug to me, at least.
This is also reported upstream:
http://bugs.freedesktop.org/show_bug.cgi?id=9528
Simply upgrading to a XCB-enabled libx11 build causes clients to start
hanging inside _XReply. There is a bunch of analysis at
http://lists.freedesktop.org/archives/xcb/2007-August/002961.html too.
To reproduce, download a build of Houdini 9.0 from www.sidefx.com and
run it. You will see various hangs almost immediately upon running
'houdini'.
I can help with all manner of debugging; I just don't understand X (and
in particular, libx11 and XCB) enough to do this myself.
