--- Comment #14 from kjpetrie winehq.bugs@kjpetrie.co.uk --- The bug actually started at the commit I gave, which is between 7.0 and 7.1. That is, the printing bug. Interestingly, judging by its title, this commit was intended to correct an error in a dialogue box for one application and appears to have broken a dialogue box in another!
I am about to start bisecting for the document number selection bug (somewhere between 7.2 and 7.6). I'll note my findings here for information but will start a new report so it can be handled separately without causing confusion about which bug is being worked on! It was my mistake to conclude the two bugs were the same because they both appeared between the two releases I had used and produced segfaults producing the same dialogue box behaviour.
