Try installing aLogcat or similar log viewer and check logs immediately after the crash. I'm currently having similar issues second time in a row, reflashing helped for a couple of weeks. Looks like something has corrupted some part of the directory structure as I keep getting (for example from aldiko):sqlite3_open_v2("data/data/com.aldiko.android/databases/catalog.db", &handle, 6, NULL) failed and then just Force Close. This just started happening, first with 0809 and now with the rooted repack.
