mintMenu no longer runs ...

[timk]

I see many people having a problem with this but it doesn't appear that their solutions apply to me. mintmenu DOES run if I create a brand new user. It is something related to my user account, but whenever I run it I get:

Code: Select all

The panel encountered a problem while loading "OAFIID:MATE_mintMenu".

I've done the following with no success:
* moved my .mate* out of the way
* mintmenu --reset
* verified python version (2.7.3)

There something somewhere in my mate settings or in some dotfile somewhere causing mintmenu to crash, but I can't figure out what it is ...

If I try to run it from a terminal, I get:

Code: Select all

tim@echo:~$ mintmenu

OSError: Cannot initialize new instance of inotify, Errno=Too many open files (EMFILE)

Not sure if that "too many open files" actually means anything or not. I certainly have not maxed out the open files on my system (I checked).

In my case it was something in /tmp/ mucking things up. A reboot (which clears /tmp/) fixed it.
