Sorry - for some reason this hadn't come up on my email! I'll get onto this ASAP. Fix should be in within 24 hours. Paul
(In reply to comment #1) > Sorry - for some reason this hadn't come up on my email! > I'll get onto this ASAP. Fix should be in within 24 hours. No problem. If it is OK with you it would be great if you could grant me commit permissions for mono-addins as well. I could then fix small bugs like this just by myself. I think having a co-maintainer for this package would be helpful. Looking forward to hear back from you.
