I've deleted all my settings in ~/Library/Application Support/LibreOfficeDev to start from fresh, and I see that LibreOfficeDev is causing a 100% CPU use. I've sampled the process and attach the spindump if it will be useful, the top of the stack is:

LO should not be released with this regression.
