Wiki pages with unresolved issues relating to their use of modules are automatically added to "Category:Pages with script errors", which is quite helpful. There are, however, wiki pages in the same category that show no sign of anything being incorrect, whether in the module itself or in the way it is used. No error messages appear on the page, so how do we learn what's happening. Or are there perhaps kmown issues with false positives?

P.S. The category label is visible at the bottom of pages with visible errors but invisible on pages with invisible errors, although the latter are listed on the category page and do show the category when inspected through SMW's Special:Browse. I'm beginning to suspect that this might just be an issue with MediaWiki categories lagging behind.
