Comment 6 for bug 877681

Oh! I see my confusion now. Sorry, but it appears ia32-libs uninstalled subversion (that would explain why I cannot execute it). If I try to re-install it I get the following error message:

user@host:~$ sudo apt-get install subversion | tee subversion.txt

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 subversion : Depends: libsvn1 (= 1.6.12dfsg-4ubuntu5) but it is not going to be installed
