The picture named "photo_04-30-02" has long strip in the middle. I assume there is either a problem on the CCD or images need furhter calibration.

Are those two circular things, below the solar panel electric propulsion?

Very likely yes, I saw a report earlier that mentioned xenon thrusters.

Izvestia and allegedly sources from RSC Energia report, that Egypt has lost communication with EgyptSat 2, less than a year since launch.

Egypt's National Authority for Remote Sensing and Space Sciences (NARSS) deny this.

Can anyone confirm?

EgyptSat-2 fails in orbit

In April 2015, rumors surfaced on the Internet that the EgyptSat-2 either completely failed in orbit or experienced attitude control problems. There were no official confirmation or denial from the official sources, but if the satellite was lost, it would functioned only one year out of 11-year life span in its technical specifications. It would also repeat an ill fate of its Ukrainian-built predecessor, which had also failed prematurely.

According to industry sources, an expected dual failure in the flight control system rendered the satellite completely inoperable. The spacecraft apparently stopped reacting to commands from the ground, despite all efforts of mission control.

By the end of April, the official Russian media confirmed the loss of the satellite citing unnamed sources. A report by the Interfax news agency said that both flight control computers onboard the spacecraft failed within 15 seconds of each other on April 12, 2015. According to the Izvestiya daily, the satellite failed on April 14.

If the Progress failure also turns out be a flight computer, heads will roll at RSC Energia.
