fork() errors?  Are there any messages on the console?

texworks uses QtDBus, so it needs a DBus session bus.  If one isn't 
present (which nowadays you need for just about anything), it will start 
its own instance.

If you are using multiwindow with startxwin, I strongly recommend adding 
the following to the beginning of your ~/.startxwinrc:

eval `dbus-launch --sh-syntax`
