Comment 39 for bug 997934

Yes, quite true, I alluded to that potential problem of a flurry of warnings. But what's also a really bad idea is a software design that claims to have compared two data sets and reports no issues when in fact it failed to do so because it cannot retrieve one of the two sets. Something needs to be done to try and address this, even if it's less than perfect.

Another possibility would be to build a list of any dictionaries the document requires at the time it's loaded and determine if any are unavailable, and if so, provide a single, concise warning. This wouldn't be perfect either, since someone could change to or add a different language while editing, but at least that would be an improvement and might reduce user confusion when the spell check silently fails to work. Or maybe there's a better idea entirely. I don't claim to have all the answers, I just think this merits attention.
