GUI applications writing garbage to stdout/stderr

[Marcel Oliver]

Hallo,

there is one more thing which I found really annoying after upgrading
to F21.  I like to launch GUI applications from the command line (I
know there is some debate on whether this habit makes me a target user
of Fedora, but I am writing under the assumption that it might).

Many GUI applications write garbage to either stdout or stderr, making
the terminal windows difficult to view and navigate.  I have seen this
on earlier releases, too, but the volume being written and the number
of applications affected has increased to the extent that it is
becoming a real problem.

Some, like nemo, even keep writing messages during operation, which is
very distracting as there is sudden movement in the corner of one's
eye. 

Yes, I know that I could write, for example

  okular file.pdf &> /dev/null

but that somehow defeats the efficiency of the command line operation.

Some of the main culprints for me are nemo, evince, and okular; if I
am go looking, I can probably find many more.  The only well-behaved
application I know is libreoffice.

Are these considered bugs that I should file against the package?  Is
there a policy that applies?

Regards,
Marcel
