confirming, and ammending summary. Once upon a time, I used to be able to reliably reproduce this crash. except not today any longer. now apper seems to just silently fail for me (maybe relevant that I recently updated to kf5 5.32.0)
and fyi, this is using a ~december 2016 git snapshot (of kf5-based port)

cc'ing apol
I don't maintain Apper, whereas I did implement support for installing packages using PackageKit in Discover.
True (and thanks for that!). cc'd because someone told me you were unaware of this.
Right, i have just made a review request with a fix for this. Basically, the problem seems to have been an about half way done port away from KUniqueApplication. If i could get some tests done on this by people who use the tool, and who might be able to tell me if it works as expected, i'd appreciate it :) https://phabricator.kde.org/D5193
