I'm trying the suggestion Alexander Kabaev gave me on the previous reply.
Obviously npviewer isn't crashing anymore!
Even if I'm trying hard opening and closing furiously a lot of tab with flash 
content.

I would be happy to do that, but I don't know about .spec files, which I think 
are needed to build rpms.
And probably I'll have a lot of other deps to build, also not available as 
rpm.
I'll try to have a look during next weekend, but I think I am not be able to 
do that.
I remember about a tool, "checkinstall" if I'm not wrong, I used many years 
ago to build rpms from source tarballs.
But I don't know if it's still working. Could it be an idea?
