Sorbates are some of the biggest killers. Anything canned in syrup can be troublesome to brew with too.
Look for stuff canned in water, preferably with nothing else added except for maybe ascorbic acid. Whether or not you will be able to find that, depends on fruit in question and your particular grocers.
FWIW, that advice is based on 40-50 batches of wine, but only done 3 of beer, so take it with a grain of salt.
