Comment 1 for bug 601886

Hi Richard,

Thanks for the report.

The test suite is currently missing an automated test for multiple
translation units, which is why this was missed. I tested this within the
last couple of months, so I think this should be the only broken class, but
I'll apply this fix and add a test case for it this evening / or tomorrow.

Cheers,
Darren

P.S. The launchpad site isn't kept up to date - http://cgi.sf.net is the
main site for the library these days!
