Exception crashes subsonic left pane
An exception occurred while I was attempting to log into the Subsonic Web interface. Everything worked fine yesterday; today, when I tried to log in, the left pane throws this exception. The other panes display fine and I can search for and listen to songs using the search interface; I just can't see the list of folders.
The library has 104,688 songs and 1946GB of music. There were only three things done to the server overnight that could have changed the environment: a weekly Tuesday morning patrol read was scheduled to occur on the RAID 6 hosting the library, RealVNC was uninstalled, and the search index had its nightly 3:00am update scheduled.
I will be going on vacation later today, so I can answer questions about this issue for the next few hours, or anytime after July 9. If there is some sort of debug mode that would allow a developer to investigate the problem further, I can turn it on when I return on July 9 and get more information then.
