I experience the same problem as leetnoob.

I have power kernel 46 and v3d and if I try to upgrade Gimp or OpenOffice it reboots the phone, corrupts image file and makes MyDocs read-only. Same result is with stock and power kernel 42 and also with image v3e.
Obviously this has something to do with PR1.3, because when I had PR1.2, I could upgrade both applications without any issue.
