Can you please check the version number of jpegtran? Toxaris's plugin uses version 9, which uses a different syntax than the previous version which accepts only one file name parameter.
The old version has the following syntax:
Code:
usage: jpegtran [switches] [inputfile]
however, the new version uses the following syntax:
Code:
usage: jpegtran [switches] [inputfile] [outputfile]
If you use the new syntax with the old version, it enters an endless loop, which causes the plugin to hang.
AFAIK, libjpeg-turbo is a fork of jpegtran that uses the old syntax. I.e. you can't use it to optimize .jpeg files under Linux.
