[yubikey-personalization-gui] 'Unknown error occurred' reported - insufficient permissions

[detrout]

Apparently no one forwarded this 2016 Debian bug. It applies to 3.1.24 and the 3.1.25 version I just tried.

From: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=842194 the user reported

I inserted my YubiKey, started up the GUI, after a short delay 'Unknown
error occurred' was reported at the top-right. This is a useless error
for a user, so I dug about - it turns out that the program DOES know
what is wrong - YubiKeyFinder::diagnostics is emitted with the text 'USB
Error: Access denied (insufficient permissions)' - the supposed 'Unknown
error' is coming from mainwindow.cpp:MainWindow::keyFound, line 549,
returning the value of OTHER_ERROR (only 2 error situations are handled
here).

It'd be nice to figure out a fix.

Odds are strong this bug Yubico/yubikey-personalization-gui#72 is likely related to the problem I was having.

I came up with a solution as
