Please take a look at bug 12577#c9 - maybe this will help.
That sounds more like a Bug 12243 (similar effect, i.e. search failing when some records found have invalid ISBNs in them - same cause, only in 3.16 branch it was happening from slightly different reasons). But I think it got already fixed somewere around 3.16.7 release, by patch from Bug 13167 (commit 9990c3e8a1071bc07ffba05950d8c86c95e81064).
You are right, thx Jacek!
Marked as 'RESOLVED', as it is apparently already fixed in current 3.16.x release.
