I am running the latest git version on current Arch Linux. For some PDF files, the output of list-logical is sane. For other files, the output is:
11 1
21 2
31 3
41 4
51 5
61 6
71 7
81 8
91 9
101 10
And for yet some others, the output is:
i1 1
ii1 2
11 3
21 4
31 5
41 6
51 7
61 8
71 9
81 10
91 11
101 12
