Subject: lyxpaperview - fix redirection
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=52d51fe4339dedb69214a765439f1b09f2c6dc0c;p=features.git

lyxpaperview - fix redirection

Any time pdfviewer process write anything to stderr it's killed,
most probably due to not existing pipe to proper stderr file descriptor.
/dev/null redirection fixes the issue.
