A friend of mine came across a similar problem some years ago. After some investigation what was happening was that he had a 64-bit installation but the plug-in was only available in 32 bits.
It was some years ago and, of course, it was not on Mageia, so this might not be your problem but, I guess, deserves a verification.
HTH,
Alejandro.
install the plugin, but keeps asking to install it.
2 days ago if it worked
