[Samsung Galaxy Nexus] fubaya:
I'm not sure if this is related to Gummy or not, but I haven't been able to use either the pm or am utilities, they just segfault. I can't remember if I tried it in the early Gummy versions but I know it's been doing that for several of the later versions now. Even running "pm --help" in a terminal segfaults.

Any ideas?

# pm --help
Segmentation fault

am also segfaults with "am --help", but this is the logcat from trying to send an intent with "am -start". It seems to be the exact same as the pm logcat but I'm posting it in case someone with eagle eyes spots a difference.
