[Bug-xnee] Fwd: Buffer overflow error while replaying recorded file

[Kp]

Hi,

I'm facing a reproducible buffer overflow error while replaying
events recorded using xnee.

The recording takes place fine; there are no errors, and cnee exits
cheerfully. Then, when I attempt to replay the file, a few events take
place, and then there is a buffer overflow.

I appear to have noticed that the buffer overflow occurs only after
any event that launches a new program. For example, if I move the
mouse around and navigate my KDE main menu, those events are replayed
fine. Cnee dies only after the an event that launches a new
application.

Another odd side-effect I'm noticing is that my keyboard repeat stops
working after cnee dies as seen below. Holding down any key for
eternity produces just one keystroke. Oddly, though, if I'm running
vmware, and the keyboard is captured by a guest virtual machine,
keyboard repeats work fine within that virtual machine... - this seems
to indicate that the hardware etc. is fine, but something is stopping
X from receiving multiple keypresses when a key is held down...?

Please find below the command output when I run cnee to replay the
events. I have attached the gnumeric2.xnl file to this mail, in case
it helps.

Would be really grateful if someone could give me some answers. I've
tried the same operation on a Fedora Core 4 machine as well as a newly
installed CentOS 4 machine, with identical results. The Fedora machine
runs KDE, while the CentOS runs Gnome. No difference in operation
visible (I guess it wouldn't make a difference anyway... but too much
info can't hurt :))

Thanks a lot, in advance!
