It looks like the file is corrupt. At the end of the file (byte 187481), there's an "xref" line followed by "1 7". The 1 indicates that the first object number in the cross-reference table will be 1, and that there are 7 entries (the next seven lines). However, the next seven lines are numbered from 0 rather than 1.
The "1 7" is invalid -- according to the spec, if there's only one cross-reference table (and this file only has one), it has to start with 0. PDF::API2 assumes that the 1 is intentional and doesn't return an error. Since Adobe Reader opens it without complaining, it looks like it assumes the 1 is a mistake and also doesn't return an error.
If you change the "1 7" to "0 7", the file will open properly in both PDF::API2 and Adobe Reader.
