I send the following message to both the [popen] and the [shell] externals: 

[cd /usr/lib/pd/extra && ls -al > ~/Desktop/foobar.txt]

when sent to [popen] it crashes Pd
but sending it to [shell] worked fine

below is the crash report (pd -stderr) after sending it to [popen]
FYI: I got rid of the [moonlib] version of [popen] as well as its help file 
as you can see the flatspace one is being loaded

tried /usr/lib/pd/extra/flatspace/popen.pd_linux and succeeded
