That might be caused by Qt being compiled to use the built-in MIME database, 
which was recently switched to a non-GPL variant. We've discovered numerous 
gaps in it. I think the bzip2 one was patched, but please retest with the 
latest Qt (6.9 beta), and if not, file the issue at bugreports.qt.io.

If the application is open source and GPL-compatible, you could also simply 
redistribute the XDG mime database with your application, overwriting the 
limited Apache Tika database Qt needs to supply. It compresses very well with 
rcc.
