Package manager has died

I got mail from a user who has a lot of apps installed that he has problems when my app gathers activity info with this code:

getPackageManager().queryIntentActivities(mAinIntent, 0)

whole source here: https://github.com/ligi/FAST

this is what happens

there seems to be a problem that I am running against the 1mb border, but how to get out of there? How else can I get the needed info? Is there a way to chunk up the data?

I ran into this error a while ago with the same user input. Though my thrown event was different. I ended up catching the exception and reporting back the user gracefully that there were too many apps installed with the ability to handle . Out of several hundred thousand installs I have only seen this error off-handedly less than five times for a project, I know that isn't an excuse but some devices just don't have the heap to handle indexing the intents of each application installed on the device.
