There appears to be a problem with the setup of some of the gain sliders (see for example mixer gain for Funcube Dongle Pro)

When switching from an Ettus B210 (where I was changing the PGA0 gain setting in the GUI) to an Ettus USRP2+WBX I had the following error on starting gqrx which may be related to what you have seen with the Funcube Dongle Pro:

m@mbu:~$ gqrx

The fix was to comment out the gain setting in the config file at '~/.config/gqrx/default.conf' and restart gqrx:

gains=@Variant(\0\0\0\b\0\0\0\x1\0\0\0\x6\0P\0G\0\x41\0\0\0\x2\0\0\0\xdd)

No, this issue is purely cosmetic and does not have functional consequences.

See issue #125 instead.

I can not reproduce it anymore.
