Crash when changing frequency (QT?) #1137

Open kevontheweb opened 2 years ago

kevontheweb commented 2 years ago

Hi I am trying to use gqrx (v 2.15.9) on fedora with an rtl-sdr dongle.

I have got it to detect the sdr and open, when I hit play everything seems fine but as soon as I try to change to frequency (using the square blocks for each digit at the top of the window) the program crashes.

this is the output when I run it from the terminal

Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt.
You must not let any exception whatsoever propagate through Qt code.
If that is not possible, in Qt 5 you must at least reimplement
QCoreApplication::notify() and catch all exceptions there.

It seems like it might be QT related.

Hello.

rtlsdr_demod_write_reg failed with -9 r82xx_write: i2c wr failed=-9 reg=17 len=1 r82xx_set_freq: failed=-9

This crash does not look Qt related. It's more likely libusb/librtlsdr related. librtlsdr fails to write R820T registers and throws an exception. Then Qt does not know, what to do with this exception.

Try running gqrx under gdb. If it crashes under gdb too, post gdb output and backtrace here.

I get the same problem, but running Gqrx 2.15.8 on ubuntu 22.04 LTS. Cubic SDR does the same thing and the last lines are below: SDRThread::readStream(): 2.

vladisslav2011 commented 1 year ago

@bjvt LibUSB error -9 (EPIPE) usually means, that the device was disconnected during transfer. It may be a bad cable, loose connection or insufficient power. That's not a Gqrx issue.

nickoe commented 1 year ago

Given there is no more updates on this, and it is a segault, an there is not backtrace attached. Maybe just close this bug by now?

argilo commented 1 year ago

Even though the root cause appears to be outside Gqrx, I left this open because there appears to be a problem in Gqrx also:

Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt.

Gqrx should not allow exceptions to bubble up to Qt.

vladtcvs commented 9 months ago

Also have such issue when change frequency. I think in case of hardware problem Gqrx should show message, not crash

nickoe commented 9 months ago

@vladtcvs backtrace?
