(the attached file is the 7Z-ppmd compressed SPS profiler output.)

BTW, this is a regerssion, as this definitely wasnt present about 5 months back.

Tentatively adding in Core:Imagelib .

Could you try isolating the range with http://mozilla.github.io/mozregression/ if that's the case? mozregression --good=2013-06-4

Also note that links to Cleopatra profiles are usually easier to deal with.

I tried to directly "share" the profile, but i got a "error 0". So i had to save it to disk, and compress and upload.
