I checked only two of the .bug.html files. They show buy-it-now articles, not auctions. Esniper cannot handle such articles. If you want to buy any of these, simply buy it.
Please copy the bug report message. It tells where in the code the error occurred and other useful information.
Probably ebay has changed something which makes esniper print a bug report instead of a normal error message. As this is a minor problem related to a mis-use, I won't take the effort to analyze the problem without complete bug report information.
