Bug wranglers at bugs.kde.org won't appreciate such explanation though:
"Revert r1135987: the build-time dependency should only be a minor release of
Qt (4.6) not a patch-level release (4.6.3).
Qt maintains forward and backward binary compatibility within minor releases,
so the patch-level releases are completely interchangable at runtime. People
should aim to use the latest patch-level release anyway in order to get
The question is: who cares whether Qt minor releases are interchangeable or
not so that we can just specify minimal required dependencies to ensure only
that stuff compiles?
"the build-time dependency should only be a minor release of Qt " - is this
policy written anywhere? Why is it more important that code compiles than
providing better user experience? I think it's fundamental question.
If one of goals of KDE community is striving to provide the best user
experience by any means necessary and if bumping version of dependencies is
guaranteed to help here for many users compiling KDE from source and actually
giving a hint for packagers, maybe it should be doneTM.
Also, as a potential bug reporter, I couldn't really accept such bug reports
being RESOLVED (doesn't matter whether UPSTREAM or WONTFIX), because what it
actually means is "dontcaregoaway". Such bugs reports are valid because
they're filled against properly built package (with respect to its build
dependencies). It helps alienating community.
