Unable to adjust date/time of photos
Mandatory: Shotwell version the issue was seen with
The expected behaviour
After adjusting the date/time of a photo in the "No Event" section, the photos should disappear from the "No Event" section and be located under the appropriate event (in this case categorized by year, month)
What was actually happening
For certain photos, the adjustment seems to occur correctly but the photos from the year 1980 stay in the 1979 event and a series of over 800 log messages are received stating "g_date_get_day: assertion 'g_date_valid (d)' failed"
Steps to reproduce the issue
I have generally had success with adjusting the date/time of photos which were, for example, scanned from old film prints. The issue seems to be isolated to a few photos (so far). The faulty behaviour is reproducible on my instance but I don't know what caused it to occur.
