Oh, just noticed that Linux/Documentation/dvb/README.dvb-usb reads:
============================== 2. Known problems and bugs
- Don't remove the USB device while running an DVB application, your system will go crazy or die most likely. ==============================
So I guess that this is a "known issue".
