I thought I'd 'advertise' this bug on the list so more people see it: http://bugzilla.open-bio.org/show_bug.cgi?id=2117 I don't want to make the next 1.5.2 release candidate until its fixed. Does anyone have any idea about it? Even if you can't fix it, just explaining what's (supposed) to be going on would help a lot. Thank you, Sendu.
