Hi Cheyenne,
Thank you for such a detailed and well documented report.
This looks like a regression in 1.5 for Linux. However I can't say more until I finish reinstalling my workstation (Fedora 11) and all virtual machines.
As soon as things "stabilize" and I can make normal tests again, I'll investigate this problem and let you know what I find. Anyway count with it fixed in the next version, of course.
