In some cases when clicking on an image, pdf or a javascript that pops up a window, a new, empty tab is opened as well. Here is an examples: http://alpinet.org/main/foto/top_ro_t_topul-foto_item_1_what_list.html click on any picture, you will see a new window witht he picture and an empty tab near of it. I will add some examples as I run into them.
Please let me know if you can find a way to reproduce it. I suspect I know what it is (double-click events getting propagated up to the tabwidget) but I would like a way of testing before making the change.
Fixed in r861259.
Let's reopen it as I can give an example for the "pdf" part: http://www.insse.ro/cms/rw/pages/comunicate/arhivasomaj.en.do click on any link that contains a pdf. A new tab "Loading" will appear and a dialog asks you to open the file in okular or save it. Whatever you chose, the Loading tab will stay there until you close it.
Can't fix. If we don't open the tab immediately, konqueror appears unresponsive (been there, tried that, see Bug 163628). So we have to open the tab immediately, even if we (in rare cases) are not going to use it because we are firing another application instead. There is no choice there. Try it in Firefox, it does exactly the same: you get a "Loading" tab, that ends up being unused. And cleaning up the unused tab automatically would lead to unexpected jumping behavior, confusing users when they are about to close the tab or type a new url or switch tabs etc.
Firefox indeed opens the new tab, but closes as soon as the dialog to choose the application that opens the file appears.
OK, I guess that doing it when popping up the dialog (just before, or even better, just after) is a way to avoid the race where the user would be clicking on the "close tab" button just after we delete the tab (and therefore closing another unrelated tab). This seems like a good solution. Reopening (but no time for this right now).

Assuming this is fixed due to comments #8, #9 and #10. If the issue still exists in Konqueror 4.8.4 or later, please reopen.
