Comment 19 for bug 519938

@Michael: you should be running Docky with the '--debug' flag set, for more output. Also if it freezes, open a terminal and run:

kill -SIGQUIT $(ps x|grep Docky.exe|grep -v grep|awk '{ print $1; }')

Which should cause a thread dump to appear in Docky's terminal. If you auto-start Docky, that output most likely is in ~/.xsession-errors (please only give us the tail end of the file relevant to Docky, it is typically huge).
