That's an odd location for the packaged binary?

bitcoin-qt's working fine for me with the same versions of the libraries
as you have, so I'll downgrade this report.

Some things you might like to try if you haven't already:

 - try running
    /usr/lib/x86_64-linux-gnu/qt5/examples/gui/analogclock/analogclock
   from qtbase5-examples to see if simple qt programs fail?
 - running "bitcoin-qt -regtest" to eliminate downloading the blockchain
   and contacting peers while debugging
 - installing bitcoind, and trying it in headless mode to avoid qt and
   graphics related bugs
 - use "ssh -X" to get into your new desktop from somewhere else, and
   run bitcoin-qt from there, to perhaps eliminate any problems related
   to graphics drivers?

Have you tried installing the qtbase5-dbg and related packages? That
seems to give me useful debug info.
