Comment # 6 on bug 967006 from Michael Andres

@mls: I'm out of office until Monday. Maybe you have some time to look at the
testcase:

testcase and log (LIBSOLV_FULLOG) are in ~ma/Export/bnc967006; job: update all
packages

MozillaFirefox-45.0-3.1.x86_64 (from repo mozilla) seems to be a valid update
candidate 
for the installed MozillaFirefox-45.0-2.1.x86_64. The presence of application
metadata 
prevents the solver from selecting it.

Removing the application data from the tescase, it works as expected
