Comment 59 for bug 987060

The problem for me seemed to have been caused by having a single very large PDF on my Desktop. Even after stopping hud-service from executing I noticed that nautilus was consistently using 15% of one CPU core, but as soon as I moved that PDF somewhere else the problem went away. I've now allowed hud-service to run again, rebooted, and things appear to be working nicely again.

Observations:

 - Why is generating the preview icon for a large PDF so costly? Surely only the first page should be read and used for that purpose?
 - Surely these preview icons should be cached?
 - I think even if generating the preview icon is expected to be costly, there is a bug here as there is definitely a memory leak + the CPU usage stayed consistently high for hours. Surely the process should finish and then the CPU usage should drop away again?
