OK, I will try, but I still can't update libbladerf, as it will not work on my Kubuntu 12.04 LTS due to the libusbx thing. Anyway at the moment I am in the process of setting up an additional vm with Kubuntu 13 latest release, hopefully this will allow updating it all.
I will let you know what happens
Information on the latest releases, and bladeRF updates
Yesterday I installed a fresh virtual machine, Kubuntu 13.10, 32bit. Gnuradio, osmo-stuff, bladeRF, gqrx, all from the sources to the latest versions, but firmware and FFPGA of the bladeRF still the older versions. Again I got the swapped IQ thing, together with strong image bleeding to the other side. Then I gave bladeRF a -L x, flashed the firmware, restarted the board, flashed the FPGA, and got a failure on the first attempt. On the second attempt it ran through, and now reception was OK, no swapped I and Q, no images. So I assume that something has changed regarding the inner workings of bladeRF, requiring to update both the bladeRF library/tool package and the EEPROM content. Still have to confirm that the Windows behavior is now wrong, but I guess so, judging from the first tests with the new EEPROM content.
