I've run into some trouble while trying to run applications.  Things
like this have been happening in Ubuntu from time-to-time and I thought
it was because I'm using the experimental window manager "compiz".  But
now on theis Fedora 9 system, I'm running strictly "out of the box" and
it dies.  Fedora 9 introduced the beta version of xorg and that was one
of the reasons why I gave up on Fedora and started using different Linux
distributions.  If you think this is just an xorg flaw, cool!  I feel
even more vindicated.
The crucial patch I found that was needed for BLT 3.0 (CVS) is here:


The `deep' change (as opposed to the crud that needed to get a compile), is the addition of the inputStyle slot for Tk 8.5. I see the patches for BLT 2.4 for Fedora 9 distributed in the SRPM has that, but it also has a whole bunch of other changes too. Certainly a bug in the X11 stuff in BLT could (and probably is) creating the problem you see. I was having actually crashes not X complaints but that was on x86_64.

Sounds like you aren't getting a useful debug trace because X11 is not in sync with the program. If you find the call to XSynchronize and move it outside the following #endif, you can force it to be in sync. (hack)
