I got the latest updates to both LXDE and pcmanfm, as well as a whole bunch of security updates and a couple kernel updates for Lubuntu 12.10. Now, odd things are happening.
When I highlight a file in pcmanfm and hit the "alternate menu" button (the one on the right side of the space bar between the Windows and Ctl keys), the menu that appears lists the options as if nothing is highlighted. I frequently use the keyboard to bring up right-click options, so this is very inconvenient. A right-click itself seems to work normally.
Also, no file on the desktop can be accessed from the desktop. If I right-click the desktop or any files on it, both pcmanfm and LDXE crash. If I try to open a file on the desktop by either double-clicking it or highlighting it and pressing Enter, both pcmanfm and LXDE crash. I can move files from the desktop to another folder and access them, but accessing anything on the desktop will cause a crash.
Finally (so far), the "Shutdown" panel icon and the "Logout" menu item have both stopped working. Clicking them does nothing anymore, where they used to bring up a menu giving me the option to log out, shutdown, restart, etc.. Now to shutdown, I have to bring up a terminal and run a shutdown command directly.
Has anyone else had these issues since the latest updates, and if so, how did you fix them?
