I think it is. And this one is even better as calling /sbin/ldconfig
afterwards doesn't revert it.

Before ldconfig call in qt %post:
 /usr/lib64/libQtCore.so -> libQtCore.so.4.5.0
 /usr/lib64/libQtCore.so.4 -> libQtCore.so.4.5.2
 /usr/lib64/libQtCore.so.4.5 -> libQtCore.so.4.5.2
 /usr/lib64/libQtCore.so.4.5.0
 /usr/lib64/libQtCore.so.4.5.2
 /usr/lib64/libQtCore_debug.so -> libQtCore.so

After:
 /usr/lib64/libQtCore.so -> libQtCore.so.4.5.0
 /usr/lib64/libQtCore.so.4 -> libQtCore_debug.so
 /usr/lib64/libQtCore.so.4.5 -> libQtCore.so.4.5.2
 /usr/lib64/libQtCore.so.4.5.0
 /usr/lib64/libQtCore.so.4.5.2
 /usr/lib64/libQtCore_debug.so -> libQtCore.so

It seems that ldconfig is comparing everything (including symlinks)
providing libQtCore.so.4 and libQtCore_debug.so comes out as last. It
doesn't point to the same file as the original symlink, so it's
changed. Using ldconfig -X should avoid it.
