Summary: pix_write writes black jpegs when the save path is too long

Initial Comment:
With the path included in the file I always get the same behaviour, black images of the right size. Even if I send "640 480" to the correct inlet the behaviour is the same. 

So I tried changing the path/filename, and BOOM everything works again. 

/home/bbogart/Projects/iat-svn/bbogart/soos/trunk/test-captures/mountains/cap 

will not work (I did not try making a fake directory named like this for testing, but I suggest you give it a try to see if you get the same behaviour.)

BUT this path/filename DOES work: 

/home/bbogart/Projects/iat-svn/bbogart/soos/trunk/test-captures/cap

Interesting eh? 

Also this is the source of the extension bug, If I use this message: 

file /home/bbogart/Projects/iat-svn/bbogart/soos/trunk/test-captures/mountains/cap 0

I get a bunch of black JPEGs! where 0 is named .tif. 

If I use this (the same directory called from a relative path:

file test-captures/mountains/cap 0

I get a bunch of properly labeled TIFs not JPEGs. 

I guess the message/symbol is too long and causing problems?? I suggest trying to write to a file in a directory with 10 slashes, that should cover the bases!
