Bug#1025675: TIAtracker 100% CPU usage (QThreat) - no track loaded

[Κρακ Άουτ <krackout@gmx.com>]

Package: tiatracker
Version: 1.3-3

Debian GNU/Linux bookworm/sid
Kernel: Linux 6.0.0-5-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.0.10-1 (2022-11-26) x86_64 GNU/Linux
libc6: 2.36-6
libqt5core5a: 5.15.6+dfsg-4

ALSA only

As soon as TIATracker is started, it reaches 100% CPU usage. It keeps using 100% of CPU (1 logical processor) for as long as it remains open; even without any track loaded or playing. Apart from CPU usage it seems to work as it should, no other issues.
I tried to start it from command line also, /usr/bin/TIATracker, I only get a warning, "Unable to open keyboard shortcuts file keymap.cfg!".

Clean installation.

Examining threats, it seems that QThread produces the problem:
