I did lose calibre for a bit there on one computer - debian unstable in a dist-upgrade I could have researched better, but all is good.

Debian bug 790005 seems ended for me, I was able today to "apt-get install calibre" and all dependencies quite smoothly.

(Yes, of course on my old-stable debian I use the binaries.)

EDIT: Not a flaw per se, When the bug in underlying QT libraries was fixed, the Debian Calibre team had upgraded to 2.31 Actually quite impressive for them these days.
