I occasionally found this problem too. I didn't dig into it any deeply, however I share my experience nonetheless.
I came up with the intuition that, at typesetting time, the LaTeX editor bumps into issues of read/write permissions within a svn-bound folder. I have then copied the folder of the documentation (say documentation/telemac2d) on a separate location outside the telemac tree. Also, I copied the folder called 'documentation/data' next to it. This is because the tex source refers to additional style information stored there, using a relative path (hence the importance of maintaining the relative position of the folders).
Doing this way I managed to typset a pdf document. At most I had to force continuing a couple of times. Some figures were missing but, I presume, circumstantially because their address was broken, in my case at least.
I am sure that there's a smarter and more thorough way to do this. However, as a workaround it was pragmatic enough to deliver something to read.
I use TeXWorks.
