There is an issue with the SmartQueue add-on's ZIP file. Perhaps this is specific to Mac OS X, but when I unzip it I get directories such as "Lib\Abacus-2.0" instead of a Lib and an Abacus-2.0 directory under it.
I haven't seen any other add-on from wowace.com have this issue. It would seem that when it is ZIP'd up that the directories aren't being stored correctly.
I can fix it by putting the directories in the right place but it isn't very convenient.
That version doesn't work for me. I get the slash in the directory name instead of two separate directories.
This is on Mac OS X 10.5. I'm assuming there may be a compatibility issue between the Windows and Mac version's of Zip used. SmartQueue is the only add-on from this site that does it though so it's kind of puzzling. Perhaps each add-on has its own procedure to zip up the files?
Files that should be in a sub-folder named "Libs" are instead given a concatenated name with a backslash, such as "Libs\AceLibrary". Files in other sub-folders are fine. Perhaps there is something special about sub-folders with names beginning "Lib".
It looks to me like the problem occurs because the svn:externals property is on the top-level addon folder. So it is probably a bug in the server script that creates the zip-files. A work-around would be to avoid using svn:externals on the top-level folder. That is, create a subfolder named Libs and set the svn:externals property on that one.
