This is a misunderstanding: I tried yesterday to install the latest rstudio from rpm (RStudio Desktop 1.1.456). I was just mentioning that the problem has been around since 2015. Indeed, with the latest rpm I get on my suse 15.0
rstudio: error while loading shared libraries: libgstreamer-0.10.so.0: cannot open shared object file: No such file or directory
and this error was already reported in the link I provided in my previous email.
