Conflict between tikz and tableofcontents

To submit my paper, I need to use the Springer document class (link below). It turns out that it creates a conflict between Tikz and ‘tableofcontents’ which causes the compiler to not create a bibliography (go figure). If I remove either the Tikz declarations, and/or the table of contents command, the bibliography runs just dandy. I spent a while trying to understand where the conflict lies, but it is beyond me.

I stripped my file to the bare minimum, and added a sample bib file. Unfortunately, the class files are too long to post here directly, but here is the link from Springer’s webpage (only the svjour3.cls and svglov3.clo files are needed).

main.tex:

The Springer document class creates a clash between Tikz and Table of Contents. 

No bibliography entry is created for~cite{A} or~cite{B}. But if you comment the tikz package declarations (lines 5--7), {bf OR} if you comment the table of contents command (line 20), the bibliography runs just fine.}
