After uninstalling LibreOffice and installing OpenOffice last month, GIMP has started scanning for Fonts on EVERY startup. This should not be necessary. I've had an issue like this before because it happened for some time every time I upgraded LibreOffice to a new version (this updates the C:\Windows\Fonts folder), but previously, GIMP only looked for Fonts on startup until I restarted my computer after the LO opgrade, and maybe once more, then it stopped scanning for fonts on startup. But this time, GIMP continues to do this after numerous restarts and I can't make it stop.

My C:\Windows\Fonts folder hasn't been touched in three weeks (the newest file was changed on December 7th). Output from Cygwin:
