Comment 13 for bug 505085

my hackaround it (remove thumbnail files older than 10 days, via cron, each hour:

sudo vi /etc/cron.hourly/tmp-cleanup

#!/bin/bash
## login disk thrashing
find /home/elink/.thumbnails -mtime +10 -type f -exec rm -rf {} \;

:wx

sudo chmod 755 /etc/cron.hourly/tmp-cleanup
