I encountered an issue while switching the Krita snap to the KDE Neon extension.
The issue is that one of Krita’s runtime dependencies (stage-packages) pulls in Qt5 from the bionic repository while Krita is being built against the kde-frameworks-5-core18-sdk build snap. When Krita starts, it tries to use the Qt5 libraries from the bionic repository, which fails because that is not the Qt version it was built against.

I fixed the issue by explicitly excluding the Qt5 libraries from the bionic repo during stage:
prime:
- "-usr/share/fonts/*"
# libquazip5-1 pulls in Qt5 from bionic as a dependency. We don't
# want it in our snap, however, because we get a newer Qt5 from the
# kde-kf5 platform snap.
- "-usr/lib/x86_64-linux-gnu/libQt5*"
- "-usr/lib/x86_64-linux-gnu/libqt5*"

I suspect many people will accidentally include qt5 as a dependency in their application. Is there any way to solve this issue in the extension itself; or warn the developer of this issue during a build?
