Pioneer receiver remote command hangs Flirc every time

[minimum]

Hello dear authors of Flirc,

I have just purchased the Flirc IR receiver and using it in conjunction with Remote Buddy 2 on macOS Mojave on a Mac Pro 5,1 and a Pioneer VSX909RDS receiver. Pretty old, but very good devices. Now I found the Remote Buddy IR signal recoding function to sometimes not record the right command, but after a couple of tries it usually works. But there is one command on the remote of the Pioneer that for some reason after recoding in RB2 and attempting to play it back hangs the Flirc. Attaching a Log file from Flirc GUI so you can see.

Which one is the cause of the hang?
