adb shell root@android: # cd /data/anr root@android:/data/anr # ls -l traces.txt -rw-rw-rw- system   system      76808 2013-04-05 13:03 traces.txt root@android:/data/anr # 

-rw-rw-rw should see (it means permissions read , write)

if see different, do

root@android:/data/anr # chmod 666 traces.txt 

ps device must rooted, otherwise unable problem :)
