The file you have problems with is added to Dia in 2005. Maybe it is invalid since than, but I'm expecting an issue either with your checkout (some transfer problem, wrong git flags set) or with the libpng version on your system.
I have multiple checkouts on various operating systems and did not yet see such an error.

    Moved changes from branch to trunk.  0.93 is hereby finalized, 0.94 is next.

Given that you only get the error at install time you seem to have been able to build Dia before. What did change since than? What operating system?

Pasting "IDAT: invalid distance too far back" to google gives:
FYI: libpng16 won't be able to show some broken icons libpng15 was still able to
http://www.gossamer-threads.com/lists/gentoo/dev/271064

So the issue might indeed need solving on Dia's side.

Making this in Arch Linux. Haven't built this for a couple months, just pulled the recent git and tried to make it. Checked it out a couple times to make sure I had a clean copy of the repo.

thank you, this exactly the case for me, and I use a newer version of libpng16.

if nobody is willing, I will try to fix this image file tomorrow, and afterwards report my findings.
Comment 7 Evgeny Bobkin 2013-09-12 07:31:34 UTC 
I have corrected the connectable.png file and afterwards was able ti build dia successfully.
