It is a tricky thing in shell, you need to understand it well.  Here it is.

ekiga writes at descriptor 2.

Your command changes descriptor 2 to use the same as 1, i.e. screen 
output, afterwards changes the descriptor 1 to use the file.  It does 
NOT changes 2 to be the same as 1!!

Use ekiga -d 4 2>/tmp/ekiga.dmp.

echo writes at descriptor 1, hence this works.

Damien, I think we should add it, right?
