I suppose this is related to unconditional SSE2 requirement in new Qt
libraries, (bugs #792594, #794739), for which I thought I had clarified
the conditions and for which I've provided patches already, but also for
which I'm not willing to sign the CLA.
This means that Qt and any application using those specific bits, will
not run at all (silently) in Stretch on any AMD-based i386 CPUs, nor on
older Intel ones, which I'd assume is a pretty big percent of the i386
park.
I think the same is affecting Chromium, which I'll need to fix too.
I've got local packages for the Qt Declarative stuff which I could
publish if there's demand.
Thanks,
Guillem
