Comment # 1 on bug 1191777 from Dominique Leuenberger

This is a false positive, 

the SLPP clearly states that multiple libraries matching the same over suffix
are allowed in one single package

in case of libpango-1_0-0:

> rpm -ql libpango-1_0-0 
/usr/lib64/libpango-1.0.so.0
/usr/lib64/libpango-1.0.so.0.4800.10
/usr/lib64/libpangocairo-1.0.so.0
/usr/lib64/libpangocairo-1.0.so.0.4800.10
/usr/lib64/libpangoft2-1.0.so.0
/usr/lib64/libpangoft2-1.0.so.0.4800.10
/usr/lib64/libpangoxft-1.0.so.0
/usr/lib64/libpangoxft-1.0.so.0.4800.10
/usr/share/doc/packages/libpango-1_0-0
/usr/share/doc/packages/libpango-1_0-0/NEWS
/usr/share/doc/packages/libpango-1_0-0/README.md
/usr/share/licenses/libpango-1_0-0
/usr/share/licenses/libpango-1_0-0/COPYING


i.e the leading lib is libpango, and all the others match the -1_0-0 suffix
