Hi there, thanks for the report.
The problem here is that strange Qt API for default pathes. Previously we added "AusweisApp2_CE" as VENDOR / Organization [1]. So Qt appends the organization and searches our configuation in "/usr/share/VENDOR/AusweisApp2 [2]. As this isn't the default on unix/linux to have the organization appended we removed VENDOR. But this now leads to this problem because QSettings [3] uses QStandardPats [4] and tries to detect the organization. See old Debian patch: 0001-Disable-vendor-name.patch Of course, we could customize our own code to work-around that. But I still see that it is a bug in Qt. Qt uses wrong defaults for unix/linux environment.
