This issue is partly solved by the fix for one important root cause having been added to release v82: see also #74

The other reason this is happening is that Qiqqa does a full DB scan in this scenario and any page which has not produced any words via the OCR process will trigger a re-execution of that OCR activity.

Naturally this will retrigger OCR for any document which has empty or image-only pages without any text -- then it's not QiqqaOCR's fault that nothing was produced, yet still OCR is retriggered.

… SINGLE don't deliver due to, for example, encrypted PDF source. This is a temporary hack to ensure Qiqqa doesn't repeat OCR activities ad nauseam (jimmejardine#129 , jimmejardine#135 , jimmejardine#73 , etc.)

- the previously added extra OCR text files' sanity checks (zero-sized areas of words, etc.) seems to pay off. At least we've observed quite a few OCR files/pages being retriggered for OCR as Qiqqa uncovers these zero-sized word areas while refreshing for Expeditions
- added a few more UI-thread-or-not Assertions.
