Aquamacs File mode specification error

I'm not sure what I did, but all of the sudden, I am getting a bunch of errors when I perform various operations in Aquamacs. For example, when I try to open a C file, I get the error "File mode specification error: (wrong-type-argument number-or-marker-p nil)". If I turn on the debugger, I get the following stack trace:

Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil)

  find-file("~/.cabal/../repositories/ghc/rts/eventlog/EventLog.h" t)

  command-execute(find-file)

Anyone have any ideas as to what might be going on here?

Solution

  • OK, so I have no idea what happened, but I was able to fix it by doing a (very) clean reinstall. I first deleted the application folder, and then did a recursive find for any Aquamacs folder in the file system. 

    find . -regex "Aquamacs.*" -maxdepth 5

    was able to give me a listing of all such files. There are a bunch of cached preference directories that do not get deleted when the application is uninstalled. I first tried using App Cleaner, which wasn't able to get all of these. After I deleted every Aquamacs related directory, and reinstalled, it worked just fine.
