ValueError initializing pages

[dankeemahill]

I get a ValueError: Cannot convert <PDFObjRef:4> to Decimal. when accessing the pages of this pdf with pdfplumber==0.5.5.

I notice the pdfplumber.open call seems to run much quicker on this file compared to other files that don't raise this error.

pdf = pdfplumber.open('Hays TX 11-8-2016+hays+county+total+canvass.pdf')
pdf.pages

Big thanks for flagging, Dan! Just pushed a fix, which should now be available in v0.5.6. The PDF you've referenced now seems to load fine for me. Let me know if you find otherwise.

I also was able to init pages on the referenced PDF with v0.5.6. Thanks! ✅
