Bug#945115: armagetronad does not find itself (and fails to start)

[boffi]

Package: armagetronad
Version: 0.2.8.3.4-3
Severity: important

Dear Maintainer,

I tried to start the program, the following message was printed
-------------------------------------
Error: Error in tString GeneratePrefix() in ../../src/tools/tDirectories.cpp:1359 : 
        Relocation error. The binary was supposed to be installed into /usr/games and found itself in  and could not find out what this means for the prefix /usr.

-------------------------------------
and I was back at the shell prompt. This happened every time I tried
after the Nov 17 update.

Regards, g
