The (long) Docker test case, instead of running hex, triggers the Hex GUI popping up with an error message:

*Error* A maximum of 3 PDB files can be given on the command line

The test case then reports a failure:

FAILED: urfin 1A2P_1-1A19_2_hex
Job details:
Command: //usr/local/lib/hex/bin/hex -ncpu 2 -nice 0 -noexec < /tmp/tmphWPHoZ_test_docker_1008/1A2P_1-1A19_2_hex.mac > /tmp/tmphWPHoZ_test_docker_1008/1A2P_1-1A19_2_hex.mac.log

<type 'exceptions.IOError'> in Docker.py line 475:
(2, 'No such file or directory').

But then continues and finishes (falsely) as "OK".

To reproduce:

python Biskit/Dock/Docker.py

System:

* Suse 10.2 AMD64 and
* Ubuntu 7.04 32bit

Workaround:

None.
The fact that the same test case did work earlier on, means that this must be related to more recent changes in the code.
