If this is ps's doing, then this violates posix and sus. Posix/Unix 
programs should only print critical errors to stderr (strace and ltrace 
are not posix/unix programs). In that case you should file a bug report 
with SUSE.

What happens if you run the command as it is in the code and pipe stdout 
to /dev/null? It might be a reading/opening error in the plugin after all.
