This specific incompatibility hints at Sparkle's pickiness about update
archive formats. I recently released an update according to all the
standard protocols, and light tests indicated all was well. Users,
though, began complaining that they were getting "Improperly Signed"
errors. I traced this down to the fact that the most recent update was
compressed using Path Finder (http://www.cocoatech.com/) rather than
Apple's Finder; I re-rolled the application using the Finder, and all
was well.

Interestingly, both files--the dysfunctional Path Finder one and the
functional Finder one--were supposedly vanilla .zip files. When Path
Finder compresses, it shows a little "Powered by StuffIt™" notice at the
bottom, though I'm not sure how that should invalidate the update.

In case you're interested in investigating the problem, my appcast is at

The original, inoperative Path Finder package can be found at
http://fountainpen.sourceforge.net/update/Leland-PathFinder0.7.1.zip
With the DSA sig. that should have worked:

And the new, Finder-compressed package is at
http://fountainpen.sourceforge.net/update/Leland-FP0.7.1.zip

Again, my specific issues have been resolved, but this is an interesting
oddity.
