Hi,
[ please keep me on the Cc:, I'm not on -devel atm ]
this is driving me nuts. moonlight segfaults on start up if libGL.so
is utah-glx's instead of regular mesa's. I have recompiled the
bloody thing against utah-glx's libGL.so (it was using some Mesa
extension that utah-glx doesn't provide) and now I'm dealing with
what seems to be a documentation problem... compiled in `development
mode' (that means don't strip the thing a behave a little different),
I'm getting:

error_code = 8 '\b', request_code = 1 '\001', minor_code = 0
'\000'}
Error code 8 is (X11/X.h):
#define BadMatch 8 /* parameter mismatch */
but XInternAtom(3x) says:
XInternAtom can generate BadAlloc and BadValue errors.
wtf!
Even more confusing, XRequest.1 is X_CreateWindow. X_InternAtom is
XRequest.16... arrrrggghhh! There's a XCreateWindow a few lines
before the call to XInternAtom, but none of the documented reasons
for a BadMatch generated by XCreateWindow are met.
Help? Anyone?
