The panel seems to have messed up for someone using Ubuntu Dapper with xfce4-panel 4.3.30svn+r20393. Turns out the problem was that while coding a plugin, an extra file in ~/.local (an .swp file, specifically) caused the scanning to stop, so newly installed plugins were not shown in the list of available plugins. It seems like the panel scanning should be limited to .desktop files?
Yes indeed. I read the mail to the xubuntu list. Something needs to be done, but I'd like to find out why it didn't simply contimue, first. Thanks for putting up the report.
(In reply to comment #1) > Yes indeed. I read the mail to the xubuntu list. Heh, I should have guessed. I actually don't, and only saw the bug on Launchpad, so I wanted to make sure it was escalated. I am (obviously) running Ubuntu Dapper also, so let me know if there's anything I can do to help (short of building a package; haven't quite figured that out yet).
Fixed with revision 20525. Silly mistake.
