Comment 5 for bug 292648

Very hard here to see where is the problem since the libraries are there, ldconfig does not seem to fail and the package seem correctly installed. I can't see any other exemple of this problem in Google, so that's unusual. I'm pretty sure that the problem is not gnucash itself but something broken in the library system of your installation (or something broke normal permissions of files). However, I don't have necessary knowledge to help you search more on this. I can only tell you that backuping your home directory and re-installing ubuntu would be a definitive solution to the problem since no other users have this problem.
