Crash on startup

[Rua]

Ever since the update 2.11.2, Gqrx no longer runs and crashes on startup. When I delete the default.conf file, this is the console output I get:

I'm using an RTL-SDR dongle, but the same happens whether I have the dongle connected or not.

I'm sorry to hear that, but that's all I can tell you unless you provide me with details.

[Rua]

What other details should I provide?

@Rua How about the actual crash line? Sofar we only know that you deleted the default.conf file..

Have you selected the right signal source and audio device in the configuration dialog?

Btw: you might get better support if you would check the mailing list/google group for GQRX first.. You can find more details http://gqrx.dk/user-support

[Rua]

There is no configuration dialog, the program crashes as soon as I run it and nothing appears other than this console output. There is no output to suggest an error happened, I just get put back to the command prompt.

What other details should I provide?

We distribute gqrx in 11 different forms for different platforms. At the very least we need to know about your environment, like operating system, method of installation, etc. In this case it would also seem relevant to know which version of gqrx used to work for you and whether you can confirm that a binary for that version still works. For most platforms we now have standalone binary packages, so it is possible to run different versions without installation.

[Rua]

Never mind. I restarted the system and suddenly it all works again. Really weird.

Ok, good :)
