Comment 4 for bug 1185985

The following workaround allows viewing the bills screen in our 2.3.7 system without producing the error when the patron has large numbers of bills.

Set the org unit setting "Uncheck bills by default in patron billing interface" (ui.circ.billing.uncheck_bills_and_unfocus_payment_box) to TRUE. When set to TRUE, the individual charges aren't selected by default, so there's nothing to tally and no error pops up.

Once the screen is loaded we are able to select the bills and they get tallied up without the error.

Not sure about setting this to TRUE for libraries, since they'll need to select charges before paying them, but we do have this set for central site, so we can fix these patrons easily when they're reported.
