The PPAPI2NPAPI wrapper fails to work in my openSUSE system.

I have installed chromium-pepper-flash, and with the package installed. After
restarting Firefox, go into about://plugins page, it shows no information about
Flash plugin being installed in the system.

I have an Arch Linux system installed on the other hand, with freshplayer
plugin functions properly. I made a copy of the .so file, removed the
freshplayer package in my openSUSE system, and put the .so in the plugins
directory, with Firefox restarted. Everything works fine, and in
about://plugins page it just shows the information about Flash plugin.

With the above situation, it seems quite possible that
1. my openSUSE has nothing wrong in configuration.
2. the Chromium pepper in my openSUSE system also works normally.
