Comment 4 for bug 1273407

It seems that libdbi1 and libdbd-mysql have to be the same version!

There is a mail on the german gnucash list:
 http://lists.gnucash.org/pipermail/gnucash-de/2014-January/008932.html

Due to the poster the problem dissapeared after upgrading libdbd-mysql to version 0.9

So libdbi1 and libdbd-mysql have to be the same version

The versions in trusty are:
$ apt-cache policy libdbi1 libdbd-sqlite3
libdbi1:
  Installiert: 0.8.4-6
  Installationskandidat: 0.9.0-1
[...]

libdbd-sqlite3:
  Installiert: 0.8.3-1+s-5ubuntu1
  Installationskandidat: 0.8.3-1+s-5ubuntu1
[...]

Upgrading libdbd-mysql to 0.9 will solve the problem, hopefully....
At least it did so in Debian
