SoapyRemote device frequently crashes Gqrx

[AsciiWolf]

I have an SDRplay RSPdx device connected via SoapyRemote (from my Raspberry Pi server). Everything works fine, but when I try to record the received audio (using the "Rec" button) or stream it via UDP (using the "UDP" button), Gqrx (2.17.7) crashes about 25% of the time:

Recording audio to /run/user/1000/doc/c72df64f/Hudba/gqrx_20260111_000940_445808500.wav
[ERROR] SoapyLogAcceptor::handlerLoop(tcp://192.168.0.10:55132) FAIL: SoapyRPCUnpacker::recv(header) FAIL:

SoapyRPCUnpacker::recv(header) FAIL: 
0x7fa32cb39924: -- error: unable to obtain symbol name for this frame

The same problem occurs when changing modulation, but not that often.

This issue happens with both the Flatpak version from Flathub and the RPM version from Fedora 43.

I am using the following device string:
driver=remote,remote=tcp://192.168.0.10:55132,remote:driver=sdrplay,serial=1234567890,soapy=0,biasT_ctrl=true

Different instance of SoapyRemote server, same issue but slightly different (more verbose) error:

Not sure if this is the correct place, but I can offer a bounty of 60 USD if someone manages to get this fixed (either in Gqrx or SoapyRemote - it does not matter).
